+# Docker usage instructions
+
+Docker distribution of DiscordChatExporter provides a way to run the app in a virtualized and isolated environment. Due to the nature of Docker, you also don't need to install any prerequisites otherwise required by DCE.
+
+Note that only the CLI flavor of DiscordChatExporter is available for use with Docker.
+
+## Pulling
+
+This will download the [Docker image from the registry](https://hub.docker.com/r/tyrrrz/discordchatexporter) to your computer. You can run this command again to update when a new version is released.
+
+```
+docker pull tyrrrz/discordchatexporter:stable
+```
+
+Note the `:stable` tag. DiscordChatExporter images are tagged according to the following patterns:
+
+- `stable`: Latest stable version release and maps to the latest GitHub release. This tag is updated with release of each new version. Recommended for personal use.
+- `latest`: Built from the latest commit and maps to the latest CI build on GitHub. This tag is updated with each new commit to `master` branch. Not recommended for everyday use, but you can use it if you want to try out some features that haven't been officially released yet.
+- `x.y.z` (e.g. `2.30.1`): Fixed version release and maps to the corresponding tag on GitHub. This tag is never updated once that version has been released. Recommended for use in various automation scenarios.
+
+You can see all available tags [here](https://hub.docker.com/r/tyrrrz/discordchatexporter/tags?page=1&ordering=name).
+
+## Usage
+
+To run the CLI in Docker and render help text:
+
+```
+docker run --rm tyrrrz/discordchatexporter:stable
+```
+
+To export a channel:
+
+```
+docker run --rm -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+If you want colored output, real-time progress reporting, and some other stuff, pass `-it` (interactive) option:
+
+```
+docker run --rm -it -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+Note the `-v /path/on/machine:/out` option, which instructs Docker to bind the `/out` directory inside the container to a path on your host machine. Replace `/path/on/machine` with the directory you want the files to be saved at.
+
+**If you are running SELinux, you will need to add the `:z` option after `/out`, e.g.:**
+
+```
+docker run --rm -v /path/on/machine:/out:z tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+For more information, refer to the [Docker docs SELinux labels for bind mounts page](https://docs.docker.com/storage/bind-mounts/#configure-the-selinux-label).
+
+You can also use the current working directory as the output directory by specifying:
+
+- `-v $PWD:/out` in Mac/Linux
+- `-v $pwd.Path:/out` in PowerShell
+
+For more information, please refer to the [Dockerfile](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/Dockerfile) and [Docker documentation](https://docs.docker.com/engine/reference/run/).
+
+To get your Token and Channel IDs, please refer to [this page](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md).
+
+## Environment variables
+
+DiscordChatExpoter CLI accepts environment variables as fallbacks for the `--token` and `--bot` options.
+
+- `DISCORD_TOKEN` to set the token
+- `DISCORD_TOKEN_BOT` to set whether it's a bot token (`true` or `false`)
+
+You can use these variables either with the `--env` Docker option or with a combination of the `--env-file` Docker option and a `.env` file.
+Please refer to the Docker documentation for more information:
+
+- [Docker run - Set environment variables](https://docs.docker.com/engine/reference/commandline/run/#set-environment-variables--e---env---env-file)
+
+## Permission issues with Linux hosts
+
+When bounding volumes between the container and the host, files mirrored from the Docker container will be owned by the Docker user (in most setups this is `root`). Please refer to this [issue comment](https://github.com/Tyrrrz/DiscordChatExporter/issues/800#issuecomment-1030471970) for instructions on how to override this behavior.
+
+## Build Docker images for arm on Raspberry Pi
+
+If you use the Docker image on arm (for example Raspberry Pi), you'd build the image as below.
+
+```bash
+$ git clone https://github.com/Tyrrrz/DiscordChatExporter.git
+$ cd DiscordChatExporter
+$ docker build -f DiscordChatExporter.Cli.dockerfile -t tyrrrz/discordchatexporter:latest .
+```
+
+After a while, some images are built like below.
+
+```bash
+$ docker image ls
+REPOSITORY                         TAG       IMAGE ID       CREATED              SIZE
+tyrrrz/discordchatexporter         latest    7c9ead725177   49 seconds ago       199MB
+<none>                             <none>    57f9f49d05af   About a minute ago   678MB
+mcr.microsoft.com/dotnet/sdk       5.0       72af6071941e   4 days ago           641MB
+mcr.microsoft.com/dotnet/runtime   3.1       6229bebd5a11   4 days ago           197MB
+```
+
+Among these, two images (`tyrrrz/discordchatexporter:latest` and `mcr.microsoft.com/dotnet/runtime:3.1`) are required, so you may delete the other two images.
+
+Now you can execute DiscordChatExporter:
+
+```bash
+$ docker run --rm tyrrrz/discordchatexporter:latest
+```

+# Getting started
+
+Welcome to the getting started page!
+Here you'll learn how to use every **DiscordChatExporter** (DCE for short) feature.
+For other things you can do with DCE, check out the [Guides](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Readme.md#Guides) section.
+
+If you still have unanswered questions after reading this page or if you have encountered a problem, please visit our [FAQ & Troubleshooting](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Troubleshooting.md) section.
+
+The information presented on this page is valid for **all** platforms.
+
+## GUI or CLI?
+
+![](https://i.imgur.com/j9OTxRB.png)
+**DCE** has two different versions:
+
+- **Graphical User Interface** (**GUI**) - it's the preferred version for newcomers as it is easy to use.
+  You can get it by [downloading](https://github.com/Tyrrrz/DiscordChatExporter/releases/latest) the `DiscordChatExporter.zip` file.
+- **Command-line Interface** (**CLI**) - offers greater flexibility and more features for advanced users, such as export scheduling, ID lists, and more specific date ranges.
+  You can get it by [downloading](https://github.com/Tyrrrz/DiscordChatExporter/releases/latest) the `DiscordChatExporter.CLI.zip` file.
+
+If you're not comfortable with **Windows'** Command-line (cmd), please choose the GUI.
+[**macOS**](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/MacOS.md), [**Linux**](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Linux.md) and [**Docker**](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Docker.md) users can only use the CLI version.
+
+**(Skip to [Using the CLI](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Getting-started.md#using-the-cli) or [File Formats](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Getting-started.md#file-formats))**
+
+## Using the GUI
+
+### Video tutorial
+
+[![Video tutorial](https://i.ytimg.com/vi/jjtu0VQXV7I/hqdefault.jpg)](https://youtube.com/watch?v=jjtu0VQXV7I)
+
+> Video by [NoIntro Tutorials](https://youtube.com/channel/UCFezKSxdNKJe77-hYiuXu3Q).
+
+### Guide
+
+1. After extracting the `.zip`, open `DiscordChatExporter.exe`
+2. Please refer to the on-screen instructions to get your token, then paste your token in the upper text box and hit ENTER or click the arrow (→).
+
+> **Warning**:
+> **Never share your token!**
+> A token gives full access to an account, treat it like a password.
+
+<img src="https://i.imgur.com/SuLQ5tZ.png" height="400"/>
+
+3. DCE will display your Direct Messages and a sidebar with your server list. Select the channel you would like to export, then click the ![](https://i.imgur.com/dnTOlDa.png) button to continue.
+
+> **Note**:
+> You can export multiple channels at once by holding `CTRL` or `SHIFT` while selecting.
+> You can also double-click a channel to export it without clicking the ![](https://i.imgur.com/dnTOlDa.png) button.
+
+<img src="https://i.imgur.com/JHMFRh2.png" height="400"/>
+
+4. In this screen you can customize the following:
+
+- **Export format** - HTML (Dark), HTML (Light), TXT, CSV and JSON
+
+Click the menu button (☰) to see more options:
+
+- **Date range (after/before)** (Optional) - If set, only messages sent in the provided date range will be exported. Only one value (either after or before) is required if you want to use this option.
+  > **Note**:
+  > Please note that the time defaults to **12:00 AM** (midnight/00:00). This means that if you choose to export between Sep 17th and Sep 18th, messages from Sep 18th won't be exported.
+- **Filter** (Optional) - Special notation for filtering the messages that get included in the export. See [Message filters](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Message-filters.md) for more info.
+- **Messages per partition** (Optional) - Split output into partitions, each limited to this number of messages (e.g. 100) or file size (e.g. 10mb). For example, a channel with 36 messages set to be partitioned every 10 messages will output 4 files.
+- **Download assets** (Optional) - If this option is set, the export will include additional files such as user avatars, attached files, images, etc.
+  Only files that are referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using the plain text (TXT) export format.
+  A folder containing the assets will be created along with the exported chat. They must be kept together.
+
+5. Click `EXPORT` to export.
+

+
+## Using the CLI
+
+> **Note**:
+> Make sure you have [.NET Core installed](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Dotnet.md) before attempting to run the commands below.
+> **Docker** users, please refer to the [Docker usage instructions](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Docker.md).
+
+1. After extracting the `.zip`, open Command Prompt, aka `cmd` (`Terminal` on **macOS** and **Linux**).
+
+2. Change the current directory to DCE's folder with `cd C:\path\to\directory`, then press ENTER to run the command.
+
+**Windows** users can quickly get the directory's path by clicking the address bar while inside the folder.
+![](https://i.imgur.com/XncnhC2.gif)
+**macOS** users can select the `.exe`, hit Command+I (⌘I), and copy what's after `Where:` to get the directory
+![](https://camo.githubusercontent.com/3c51a904b0099c9f68a4797461d4a7914902fc04/68747470733a2f2f692e696d6775722e636f6d2f323975364e79782e706e67)
+You can also drag and drop the folder on **every platform**.
+![](https://i.imgur.com/sOpZQAb.gif)
+
+3. Now we're ready to run the commands. The examples on this page follow the Windows file path format, change the file paths according to your system.

+
+> **Note**:
+> Options with an asterisk (**\***) are required. The order of the options doesn't matter.
+
+With this command you can export Server Channels and Direct Messages.
+
+##### Basic usage
+
+You can quickly export with DCE's default settings by using just `-t token` and `-c channelid`.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555
+```
+
+##### Changing the format
+
+You can change the export format to `HtmlDark`, `HtmlLight`, `PlainText` `Json` or `Csv` with `-f format`. The default format is `HtmlDark`.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -f Json
+```
+
+##### Changing the output filename
+
+You can change the filename by using `-o name.ext`. e.g. for the `HTML` format:
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -o myserver.html
+```
+
+##### Changing the output directory
+
+You can change the export directory by using `-o` and providing a path that ends with a slash or does not have a file extension.
+If any of the folders in the path have a space in its name, escape them with quotes (").
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports"
+```
+
+##### Changing the filename and output directory
+
+You can change both the filename and export directory by using `-o directory\name.ext`.
+Note that the filename must have an extension, otherwise it will be considered a directory name.
+If any of the folders in the path have a space in its name, escape them with quotes (").
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports\myserver.html"
+```
+
+##### Generating the filename and output directory dynamically
+
+You can use template tokens to generate the output file path based on the guild and channel metadata.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports\%G\%T\%C.html"
+```
+
+Assuming you are exporting a channel named `"my-channel"` in the `"Text channels"` category from a server called `"My server"`, you will get the following output file path: `C:\Discord Exports\My server\Text channels\my-channel.html`
+
+Here is the full list of supported template tokens:
+
+- `%g` - guild ID
+- `%G` - guild name
+- `%t` - category ID
+- `%T` - category name
+- `%c` - channel ID
+- `%C` - channel name
+- `%p` - channel position
+- `%P` - category position
+- `%a` - the "after" date
+- `%b` - the "before" date
+- `%%` - escapes `%`
+
+##### Partitioning
+
+You can use partitioning to split files after a given number of messages or file size.
+For example, a channel with 36 messages set to be partitioned every 10 messages will output 4 files.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -p 10
+```
+
+A 45mb channel set to be partitioned every 20mb will output 3 files.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -p 20mb
+```
+
+##### Downloading assets
+
+If this option is set, the export will include additional files such as user avatars, attached files, images, etc.
+Only files that are referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using the plain text (TXT) export format.
+A folder containing the assets will be created along with the exported chat. They must be kept together.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --media
+```
+
+##### Reuse assets
+
+Previously downloaded assets can be reused to skip redundant downloads as long as the chat is always exported to the same folder. Using this option can speed up future exports. This option requires the `--media` option.
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --media --reuse-media
+```
+
+##### Date formats
+
+This setting changes how dates are formatted in the exported files.
+
+- The default one is `17-Sep-19 11:34 PM` - `dd-MMM-yy hh:mm tt`
+- To change it to `09-17-19 11:34 PM` use `MM-dd-yy hh:mm tt`
+- To change it to `17/09/2019 23:34` use `dd/MM/yyyy HH:mm`
+- To change it to `2019-09-17 23:34:05.6534` use `yyyy-MM-dd HH:mm:ss.ffff`
+- To change it to UTC `2019-09-18 04:34:05Z` use `u`
+- To display the time zone, add `K`. E.g. to change it to `17-Sep-19 11:34 PM (UTC-05:00)` use `dd-MMM-yy hh:mm tt (UTCK)`
+- To change it to Unix time `1568694845` use `unix`
+- To change it to Unix time in milliseconds `1568694845653` use `unixms`
+

+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --dateformat "yyyy-MM-dd HH:mm"
+```
+
+> Special thanks to [@andrewkolos](https://github.com/andrewkolos) for adding the Unix options
+
+##### Date ranges
+
+**Messages sent before a date**
+Use `--before` to export messages sent before the provided date. E.g. messages sent before September 18th, 2019:
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --before 2019-09-18
+```
+
+**Messages sent after a date**
+Use `--after` to export messages sent after the provided date. E.g. messages sent after September 17th, 2019 11:34 PM:
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --after "2019-09-17 23:34"
+```
+
+**Messages sent in a date range**
+Use `--before` and `--after` to export messages sent during the provided date range. E.g. messages sent between September 17th, 2019 11:34 PM and September 18th:
+
+```powershell
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --after "2019-09-17 23:34" --before "2019-09-18"
+```
+
+You can try different formats like `17-SEP-2019 11:34 PM` or even refine your ranges down to milliseconds `17-SEP-2019 23:45:30.6170`!
+Don't forget to quote (") the date if it has spaces!

+
+## File formats
+
+### HTML
+
+![](https://i.imgur.com/S7lBTkV.png)
+The HTML format replicates Discord's interface, making it the most user-friendly option.
+It's the best format for attachment preview and sharing.
+You can open `.html` files with a web browser, such as Google Chrome.
+
+> **Warning**:
+> If a picture is deleted, or if a user changes its avatar, the respective images will no longer be displayed.
+> Export using the "Download referenced assets" (`--media`) option to avoid this.
+
+### Plain Text
+
+<img src="https://i.imgur.com/PbUyRXD.png" height="400"/>
+
+The Plain Text format is the best option for archiving due to its small size.
+You can open `.txt` files with a text editor, such as Notepad.
+
+### JSON
+
+<img src="https://i.imgur.com/FAeSA4O.png" height="400"/>
+
+The JSON format contains more technical information and is easily parsable.
+You can open `.json` files with a text editor, such as Notepad.
+
+### CSV
+
+![](https://i.imgur.com/VEVUsKs.png)
+![](https://i.imgur.com/1vPmQqQ.png)
+
+The CSV format allows for easy parsing of the chat log. Depending on your needs, the JSON format might be better.
+You can open `.csv` files with a text editor, such as Notepad, or a spreadsheet app, like Microsoft Excel and Google Sheets.

+# Message filters
+
+You can use a special notation to filter messages that you want to have included in an export. The notation syntax is designed to mimic Discord's search query syntax, but with additional capabilities.
+
+To configure a filter, specify it in advanced export parameters when using the GUI or by passing the `--filter` option when using the CLI. For the CLI version, see also [caveats](#cli-caveats).
+
+## Examples
+
+- Filter by user
+
+```
+from:Tyrrrz
+```
+
+- Filter by user (with discriminator)
+
+```
+from:Tyrrrz#1234
+```
+
+- Filter by message content (allowed values: `link`, `embed`, `file`, `video`, `image`, `sound`)
+
+```
+has:image
+```
+
+- Filter by mentioned user (same rules apply as with `from:` filter)
+
+```
+mentions:Tyrrrz#1234
+```
+
+- Filter by contained text (has word "hello" and word "world" somewhere in the message text):
+
+```
+hello world
+```
+
+- Filter by contained text (has the string "hello world" somewhere in the message text):
+
+```
+"hello world"
+```
+
+- Combine multiple filters ('and'):
+
+```
+from:Tyrrrz has:image
+```
+
+- Same thing but with an explicit operator:
+
+```
+from:Tyrrrz & has:image
+```
+
+- Combine multiple filters ('or'):
+
+```
+from:Tyrrrz | from:"96-LB"
+```
+
+- Combine multiple filters using groups:
+
+```
+(from:Tyrrrz | from:"96-LB") has:image
+```
+
+- Negate a filter:
+
+```
+-from:Tyrrrz | -has:image
+```
+
+- Negate a grouped filter:
+
+```
+-(from:Tyrrrz has:image)
+```
+
+- Escape special characters (`-` is escaped below, so it's not parsed as negation operator):
+
+```
+from:96\-LB
+```
+
+## CLI Caveats
+
+In most cases, you will need to enclose your filter in quotes (`"`) to escape characters that may have special meaning in your shell:
+
+```
+DiscordChatExporter.Cli export [...] --filter "from:Tyrrrz has:image"
+```
+
+If you need to include quotes inside the filter itself as well, use single quotes (`'`) for those instead:
+
+```
+DiscordChatExporter.Cli export [...] --filter "from:Tyrrrz 'hello world'"
+```
+
+Additionally, negated filters (those that start with `-`) may cause parsing issues even when enclosed in quotes. To avoid this, use the tilde (`~`) character instead of the dash (`-`):
+
+```
+DiscordChatExporter.Cli export [...] --filter ~from:Tyrrrz
+```

+# Scheduling exports with Cron
+
+Make sure you already have **DiscordChatExporter.CLI** and **.NET Core** properly installed ([instructions here](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Linux.md)).
+
+You can use Cron on macOS, but [this method](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/scheduling-MacOS.md) is preferred.
+
+---
+
+1. Open Terminal and create a new text file with `nano /path/to/DiscordChatExporter/cron.sh`
+
+> **Note**:
+> You can't use your mouse in nano, use the arrow keys to control the cursor (caret).
+
+2. Paste the following into the text file:
+
+```bash
+#!/bin/bash
+# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs
+
+TOKEN=tokenhere
+CHANNELID=channelhere
+DLLFOLDER=dceFOLDERpathhere
+FILENAME=filenamehere
+EXPORTDIRECTORY=dirhere
+EXPORTFORMAT=formathere
+# Available export formats: plaintext, htmldark, htmllight, json, csv
+# /\ CaSe-SeNsItIvE /\
+# You can edit the export command on line 40 if you'd like to include more options like date ranges and date format. You can't use partitioning (-p) with this script.
+
+# This will verify if EXPORTFORMAT is valid and will set the final file extension according to it. If the format is invalid, the script will display a message and exit.
+if [[ "$EXPORTFORMAT" == "plaintext" ]]; then
+FORMATEXT=.txt
+elif [[ "$EXPORTFORMAT" == "htmldark" ]] || [[ "$EXPORTFORMAT" == "htmllight" ]]; then
+FORMATEXT=.html
+elif [[ "$EXPORTFORMAT" == "json" ]]; then
+FORMATEXT=.json
+elif [[ "$EXPORTFORMAT" == "csv" ]]; then
+FORMATEXT=.csv
+else
+echo "$EXPORTFORMAT - Unknown export format"
+echo "Available export formats: plaintext, htmldark, htmllight, csv, json"
+echo "/\ CaSe-SeNsItIvE /\\"
+exit 1
+fi
+
+# This will change the script's directory to DLLPATH, if unable to do so, the script will exit.
+cd $DLLFOLDER || exit 1
+
+# This will export your chat
+dotnet DiscordChatExporter.Cli.dll export -t $TOKEN -c $CHANNELID -f $EXPORTFORMAT -o $FILENAME.tmp
+
+# This sets the current time to a variable
+CURRENTTIME=$(date +"%Y-%m-%d-%H-%M-%S")
+
+# This will move the .tmp file to the desired export location, if unable to do so, it will attempt to delete the .tmp file.
+if ! mv "$FILENAME.tmp" "${EXPORTDIRECTORY//\"}/$FILENAME-$CURRENTTIME$FORMATEXT" ; then
+echo "Unable to move $FILENAME.tmp to $EXPORTDIRECTORY/$FILENAME-$CURRENTTIME$FORMATEXT."
+echo "Cleaning up..."
+  if ! rm -Rf "$FILENAME.tmp" ; then
+  echo "Unable to remove $FILENAME.tmp."
+  fi
+exit 1
+fi
+exit 0
+```
+
+3. Replace:
+
+- `tokenhere` with your [Token](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md).
+- `channelhere` with a [Channel ID](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md).
+- `dceFOLDERpathhere` with DCE's **directory path** (e.g. `/path/to/folder`, NOT `/path/to/folder/DiscordChatExporter.dll`).
+- `filenamehere` with the exported channel's filename, without spaces.
+- `dirhere` with the export directory (e.g. /home/user/Documents/Discord\ Exports).
+- `formathere` with one of the available export formats.
+
+> **Note**:
+> Remember to escape spaces (add `\` before them) or to quote (") the paths (`"/home/my user"`)!
+
+> **Note**:
+> To save, hold down CTRL and then press O, if asked for a filename, type it and press ENTER. Hit CTRL+X to exit the text editor.
+> [Check out this page](https://wiki.gentoo.org/wiki/Nano/Basics_Guide) if you want to know more about nano.
+
+4. Make your script executable with `chmod +x /path/to/DiscordChatExporter/cron.sh`
+
+5. Let's edit the cron file. If you want to run the script with your user privileges, edit it by running `crontab -e`. If you want to run the script as root, edit it with `sudo crontab -e`. If this is your first time running this command, you might be asked to select a text editor. Nano is easier for beginners.
+
+6. Add the following to the end of the file `* * * * * /path/to/DiscordChatExporter/cron.sh >/tmp/discordchatexporter.log 2>/tmp/discordchatexportererror.log`. Don't forget to replace the `/path/to/DiscordChatExporter/cron.sh`!
+
+> **Note**:
+> If you don't want logs to be created, replace both `/tmp/discordchatexporter.log` with `/dev/null`.
+
+Then replace the \*s according to:
+
+![](https://i.imgur.com/RY7USM6.png)
+
+---
+
+**Examples**:
+
+- If you want to execute the script at minute 15 of every hour: `15 * * * *`
+- Every 30 minutes `*/30 * * * *`
+- Every day at midnight `0 0 * * *`
+- Every day at noon `0 12 * * *`
+- Every day at 3, 4 and 6 PM `0 15,16,18 * * *`
+- Every Wednesday at 9 AM `0 9 * * 3`
+
+Verify your cron time [here](https://crontab.guru).
+
+---
+
+**Extra information**
+
+The week starts on Sunday. 0 = SUN, 1 = MON ... 7 = SUN.
+
+Be aware that if you set the day to '31', the script will only run on months that have the 31st day.
+
+> [Learn more about running a cron job on the last day of the month here](https://stackoverflow.com/questions/6139189/cron-job-to-run-on-the-last-day-of-the-month) (expert).
+
+The default filename for the exported channel is `YYYY-MM-DD-hh-mm-ss-yourfilename`. You can change it if you'd like.
+
+Don't forget to update your token in the script after it has been reset!

+# Scheduling exports on macOS
+
+Scheduling on macOS is a bit tricky, but it should work if you follow the instructions accordingly.
+
+Make sure you already have **DiscordChatExporter.CLI** and **.NET Core** properly installed ([instructions here](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/macOS-usage-instructions.md)).
+
+## Creating the script
+
+1. Open TextEdit.app and create a new file
+
+2. Convert the file to a plain text one in 'Format > Make Plain Text' (⇧⌘T)
+
+![](https://i.imgur.com/WXrTtXM.png)
+
+3. Paste the following into the text editor:
+
+```bash
+#!/bin/bash
+# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs
+
+TOKEN=tokenhere
+CHANNELID=channelhere
+DLLFOLDER=dceFOLDERpathhere
+FILENAME=filenamehere
+EXPORTDIRECTORY=dirhere
+EXPORTFORMAT=formathere
+# Available export formats: plaintext, htmldark, htmllight, json, csv
+# /\ CaSe-SeNsItIvE /\
+# You can edit the export command on line 43 if you'd like to include more options like date ranges and date format. You can't use partitioning (-p) with this script.
+
+# This variable specifies in which directories the executable programs are located. Don't change it.
+PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet
+
+# This will verify if EXPORTFORMAT is valid and will set the final file extension according to it. If the format is invalid, the script will display a message and exit.
+if [[ "$EXPORTFORMAT" == "plaintext" ]]; then
+FORMATEXT=.txt
+elif [[ "$EXPORTFORMAT" == "htmldark" ]] || [[ "$EXPORTFORMAT" == "htmllight" ]]; then
+FORMATEXT=.html
+elif [[ "$EXPORTFORMAT" == "json" ]]; then
+FORMATEXT=.json
+elif [[ "$EXPORTFORMAT" == "csv" ]]; then
+FORMATEXT=.csv
+else
+echo "$EXPORTFORMAT - Unknown export format"
+echo "Available export formats: plaintext, htmldark, htmllight, csv, json"
+echo "/\ CaSe-SeNsItIvE /\\"
+exit 1
+fi
+
+# This will change the script's directory to DLLPATH, if unable to do so, the script will exit.
+cd $DLLFOLDER || exit 1
+
+# This will export your chat
+dotnet DiscordChatExporter.Cli.dll export -t $TOKEN -c $CHANNELID -f $EXPORTFORMAT -o $FILENAME.tmp
+
+# This sets the current time to a variable
+CURRENTTIME=$(date +"%Y-%m-%d-%H-%M-%S")
+
+# This will move the .tmp file to the desired export location. If unable to do so, it will attempt to delete the .tmp file.
+if ! mv "$FILENAME.tmp" "${EXPORTDIRECTORY//\"}/$FILENAME-$CURRENTTIME$FORMATEXT" ; then
+echo "Unable to move $FILENAME.tmp to $EXPORTDIRECTORY/$FILENAME-$CURRENTTIME$FORMATEXT."
+echo "Cleaning up..."
+  if ! rm -Rf "$FILENAME.tmp" ; then
+  echo "Unable to remove $FILENAME.tmp."
+  fi
+exit 1
+fi
+exit 0
+```
+
+4. Replace:
+
+- `tokenhere` with your [Token](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md)
+- `channelhere` with a [Channel ID](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md)
+- `dceFOLDERpathhere` with DCE's **directory's path** (e.g. `/Users/user/Desktop/DiscordChatExporterFolder`, NOT `/Users/user/Desktop/DiscordChatExporterFolder/DiscordChatExporter.DLL`)
+- `filenamehere` with the exported channel's filename, without spaces
+- `dirhere` with the directory you want the files to be saved at (e.g. `/Users/user/Documents/Discord\ Exports`)
+- `formathere` with one of the available export formats
+
+To quickly get file or folder paths, select the file/folder, then hit Command+I (⌘I) and copy what's after `Where:`.
+After copying and pasting, make sure the file/folder name is not missing. If a folder has spaces in its name, add `\` before the spaces, like in the example below:
+
+- `Discord\ Exports` - Wrong ✗
+- `/Users/user/Documents` - Wrong ✗
+- `/Users/user/Documents/Discord Exports` - Wrong ✗
+- `/Users/user/Documents/Discord\ Exports/DCE.Cli.dll` - Wrong ✗
+- `/Users/user/Documents/Discord \Exports` - Wrong ✗
+- `/Users/user/Documents/Discord\ Exports` - Correct ✓
+- `/Users/user/Desktop/DiscordChatExporter` - Correct ✓
+
+![](https://i.imgur.com/29u6Nyx.png)
+
+5. Save the file as `filename.sh`, not `.txt`
+6. Open Terminal.app, type `chmod +x`, press the SPACE key, then drag & drop the `filename.sh` into the Terminal window and hit RETURN. You may be prompted for your password, and you won't be able to see it as you type.
+
+## Creating the .plist file
+
+Open TextEdit, make a Plain Text (⇧⌘T) and then paste the following into it:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+    <dict>
+        <key>Label</key>
+        <string>local.discordchatexporter</string>
+        <key>Program</key>
+        <string>/path/to/filename.sh</string>
+        REPLACEME
+    </dict>
+</plist>
+```
+
+- The `Label` string is the name of the export job, it must be something unique. Replace the `local.discordchatexporter` between the `<string>` with another name if you'd like to run more than one script.
+- The `Program` string is the path to the script. Replace `/path/to/filename.sh` between the `<string>` with the path of the previously created script.
+- Replace the `REPLACEME` with the content presented in the following sections according to <u>when</u> you want to export.
+
+When you're done, save the file with the same name as the `Label` and with the `.plist` extension (not `.txt`), like `local.discordchatexporter.plist`.
+
+### Exporting on System Boot/User Login
+
+```xml
+<key>RunAtLoad</key>
+<true/>
+```
+
+### Export every _n_ seconds
+
+The following example is to export every 3600 seconds (1 hour), replace the integer value with your desired time:
+
+```xml
+<key>StartInterval</key>
+<integer>3600</integer>
+```
+
+### Export at a specific time and date
+
+```xml
+<key>StartCalendarInterval</key>
+<dict>
+    <key>Weekday</key>
+    <integer>0</integer>
+    <key>Month</key>
+    <integer>0</integer>
+    <key>Day</key>
+    <integer>0</integer>
+    <key>Hour</key>
+    <integer>0</integer>
+    <key>Minute</key>
+    <integer>0</integer>
+</dict>
+```
+
+| Key         | Integer           |
+| ----------- | ----------------- |
+| **Month**   | 1-12              |
+| **Day**     | 1-31              |
+| **Weekday** | 0-6 (0 is Sunday) |
+| **Hour**    | 0-23              |
+| **Minute**  | 0-59              |
+
+**Sunday** - 0; **Monday** - 1; **Tuesday** - 2; **Wednesday** - 3; **Thursday** - 4; **Friday** - 5; **Saturday** - 6
+
+Replace the template's `0`s according to the desired times.
+
+You can delete the `<key>`s you don't need, don't forget to remove the `<integer>0</integer>` under it.
+Omitted keys are interpreted as wildcards, for example, if you delete the Minute key, the script will run at every minute, delete the Weekday key and it'll run at every weekday, and so on.
+
+Be aware that if you set the day to '31', the script will only run on months that have the 31st day.
+
+**Check the examples below ([or skip to step 3 (loading the file)](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/scheduling-MacOS.md#3-loading-the-plist-into-launchctl)):**
+
+Export everyday at 5:15 PM:
+
+```xml
+<key>StartCalendarInterval</key>
+<dict>
+    <key>Hour</key>
+    <integer>17</integer>
+    <key>Minute</key>
+    <integer>15</integer>
+</dict>
+
+```
+
+Every 15 minutes of an hour (xx:15):
+
+```xml
+<key>StartCalendarInterval</key>
+<dict>
+    <key>Minute</key>
+    <integer>15</integer>
+</dict>
+
+```
+
+Every Sunday at midnight and every Wednesday full hour (xx:00). Notice the inclusion of `<array>` and `</array>` to allow multiple values:
+
+```xml
+<key>StartCalendarInterval</key>
+<array>
+        <dict>
+		<key>Weekday</key>
+		<integer>0</integer>
+                <key>Hour</key>
+                <integer>00</integer>
+                <key>Minute</key>
+                <integer>00</integer>
+        </dict>
+	<dict>
+		<key>Weekday</key>
+		<integer>3</integer>
+		<key>Minute</key>
+		<integer>00</integer>
+	</dict>
+</array>
+```
+
+## Loading the .plist into launchctl
+
+1. Copy your `filename.plist` file to one of these folders according to how you want it to run:
+
+- `~/Library/LaunchAgents` runs as the current logged-in user.
+
+- `/Library/LaunchDaemons` runs as the system "_administrator_" (root).
+
+- If macOS has a single user:
+  - If you want to export only when the user is logged in, choose the first one.
+  - If you want the script to always run on System Startup, choose the second one.
+- If macOS has multiple users:
+  - If you want the script to run only when a certain user is logged in, choose the first one.
+  - If you want the script to always run on System Startup, choose the second one.
+
+To quickly go to these directories, open Finder and press Command+Shift+G (⌘⇧G), then paste the path into the text box.
+
+2. To load the job into launchctl, in Terminal, type `launchctl load`, press SPACE, drag and drop the `.plist` into the Terminal window, then hit RETURN. It won't output anything if it was successfully loaded.
+
+### Extra launchctl commands
+
+**Unloading a job**
+
+```
+launchctl unload /path/to/Library/LaunchAgents/local.discordchatexporter.plist
+```
+
+**List every loaded job**
+
+```
+launchctl list
+```
+
+**Check if a specific job is enabled**
+You can also see error codes (2nd number) by running this command.
+
+```
+launchctl list | grep local.discordchatexporter
+```

+# Troubleshooting
+
+Welcome to the Frequently Asked Questions (FAQ) and Troubleshooting page!
+Here you'll find the answers to most of the questions related to **DiscordChatExporter** (DCE for short) and its core features.
+
+- ❓ If you still have unanswered questions _after_ reading this page, feel free to [create a new discussion](https://github.com/Tyrrrz/DiscordChatExporter/discussions/new).
+- 🐞 If you have encountered a problem that's not described here, has not [been discussed before](https://github.com/Tyrrrz/DiscordChatExporter/discussions), and is not a [known issue](https://github.com/Tyrrrz/DiscordChatExporter/issues?q=is%3Aissue), please [create a new discussion](https://github.com/Tyrrrz/DiscordChatExporter/discussions/new) or [open a bug report](https://github.com/Tyrrrz/DiscordChatExporter/issues/new). Don't forget to include your platform (Windows, Mac, Linux, etc.) and a detailed description of your question/problem.
+
+## General
+
+### Token stealer?
+
+No. That's why this kind of software needs to be open-source, so the code can be audited by anyone.
+Your token is only used to connect to Discord's API, it's not sent anywhere else.
+If you're using the GUI, be aware that your token will be saved to a plain text file unless you disable it in the settings menu.
+
+### Why should I be worried about the safety of my token?
+
+A token can be used to log into your account, so treat it like a password and never share it.
+
+### How can I reset my token?
+
+Follow the [instructions here](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md).
+
+### Will I get banned if I use this?
+
+Automating user accounts is technically against [TOS](https://discord.com/terms), use at your discretion. [Bot accounts](https://discord.com/developers/docs/topics/oauth2#bots) don't have this restriction.
+
+### Will the messages disappear from the exported file if I delete a message, delete my account or block a person?
+
+Text messages will not be removed from the exported file, but if media, such as images and user avatars, is changed or deleted, it will no longer be displayed. To avoid this, export using the "Download media" (`--media`) option.
+
+### Can DCE export messages that have already been deleted?
+
+No, DCE cannot access them since they have been permanently deleted from Discord's servers.
+
+### Can DCE export private chats?
+
+Yes, if your account has access to them.
+
+### Can DCE download images?
+
+Yes, and other media too. Export using the "Download media" (`--media`) option.
+
+### Can the exported chats be shared?
+
+Yes.
+
+### Can DCE recreate the exported chats in Discord?
+
+No, DCE is an exporter.
+
+### Can DCE reupload exported messages to another channel?
+
+No, DCE is an exporter.
+
+## First steps
+
+### How can I find my token?
+
+Check the following page: [Obtaining token](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md)
+
+### When I open DCE a black window pops up quickly or nothing shows up.
+
+If you have [.NET Core Runtime correctly installed](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Dotnet.md), you might have downloaded DCE.CLI, try [downloading the GUI](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Getting-started.md#gui-or-cli) instead.
+
+### I can't open DCE. It sends me to a Visual Studio webpage.
+
+Check the following page:
+[Installation and usage](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Readme.md#installation--usage)
+
+### How do I run DCE on macOS or Linux?
+
+Check the following pages:
+
+- [macOS usage instructions](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/MacOS.md)
+- [Linux usage instructions](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Linux.md)
+
+### How can I set DCE to export automatically at certain times?
+
+Check the following pages to learn how to schedule **DiscordChatExporter.CLI** runs (advanced):
+
+- [Windows scheduling](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/scheduling-windows.md)
+- [macOS scheduling](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/scheduling-MacOS.md)
+- [Linux scheduling](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/scheduling-Linux.md)
+
+### The exported file is too large, I can't open it!
+
+Try opening it with a different program, try partitioning or use a different file format, like `PlainText`.
+
+### DCE is crashing/failing.
+
+Check the following page: [Installing .NET Core Runtime](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Dotnet.md)
+
+If you already have .NET Core installed, please check if your problem is a [known issue](https://github.com/Tyrrrz/DiscordChatExporter/issues?q=is%3Aissue) before [opening a bug report](https://github.com/Tyrrrz/DiscordChatExporter/issues/new).
+
+### .NET Core Runtime is required.
+
+Check the following page: [Installing .NET Core Runtime](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Dotnet.md)
+
+## CLI
+
+### How do I use the CLI?
+
+Check the following page:
+
+- [Using the CLI](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Getting-started.md#using-the-cli)
+
+If you're using **Docker**, please refer to the [Docker Usage Instructions](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Docker.md) instead.
+
+### Where can I find the 'Channel IDs'?
+
+Check the following page:
+
+- [Obtaining Channel IDs](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md)
+
+### I can't find Docker exported chats
+
+Check the following page:
+
+- [Docker usage instructions](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/docker)
+
+### I can't export Direct Messages
+
+Make sure you're [copying the DM Channel ID](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Token-and-IDs.md#how-to-get-a-direct-message-channel-id), not the person's user ID.
+

+  - Fixed an issue where guild categories were rendered with blank names.
+
+## v2.40.2 (27-Jul-2023)
+
+- General changes:
+  - Improved error reporting on unexpected HTTP errors.
+- CLI changes:
+  - Fixed an issue which caused a crash when trying to export a private (but accessible) channel inside a private (but not accessible) category.
+
+## v2.40.1 (21-Jul-2023)
+
+- General changes:
+  - Fixed an issue where the fallback avatar (i.e. the avatar used for when the user doesn't have a custom one set) was not resolved properly for users that don't have a discriminator.
+- CLI changes:
+  - Added the `--include-vc` option to `exportall` and `exportguild` commands, which instructs whether to include voice-channel-accompanying text channels in the export. By default, this is set to `true` to match the previous behavior. To disable the option, use `--include-vc false`.
+- GUI changes:
+  - Replaced the blur effect applied to the token text box with a password mask.
+- JSON format changes:
+  - Added the `exportedAt` field to the export metadata, which contains the timestamp corresponding to when the export was created. (Thanks [@slatinsky](https://github.com/slatinsky))
+  - Added the `roles` field to the object describing a user. This field contains an array of objects that describe the roles assigned to the user. (Thanks [@slatinsky](https://github.com/slatinsky))
+
+## v2.40 (08-Jun-2023)
+
+- General changes:
+  - Added support for users that don't have discriminators.
+  - Added a precondition check that verifies whether the requested channel contains any messages for the specified period, before starting the export process. This check works by comparing the export bounds against the ID of the last message in the channel, which is provided by the Discord API as part of the channel metadata. When exporting many channels in batches (e.g. using the `exportall` command), this check may eliminate a significant number of unnecessary API calls and speed up the export process.
+- CLI changes:
+  - Extended the `channels` command with the `--include-threads` option. When this option is provided, the command will include channel threads in the output. (Thanks [@WAUthethird](https://github.com/WAUthethird))
+  - Simplified the information in the `guide` command related to the extraction of DM channel IDs. Discord now provides a native way of copying IDs of DM channels, so the previous devtools-based workaround is no longer necessary.
+- GUI changes:
+  - Added a blur effect to the token text box, which activates when the control loses focus. This is done to reduce the risk of accidentally exposing the token when taking screenshots.
+- HTML format changes:
+  - Added support for the header markdown syntax.
+  - Added support for the list markdown syntax.
+
+## v2.39.1 (10-Mar-2023)
+
+- Fixed an issue where messages containing mentions of users that left the server (but haven't deleted their account) were incorrectly rendered as `@Unknown`.
+- Fixed an issue where messages containing video links were not rendered correctly in the HTML export. Now, they are rendered using a video player and the referenced assets are pulled if the "download assets" option is enabled.
+
+## v2.39 (25-Feb-2023)
+
+- Added an option to specify the directory path for downloaded assets. This can be used, in combination with the "reuse assets" option, to have a shared asset directory for multiple exports. In GUI, this option can be found in the advanced section of the export dialog. In CLI, it's available as `--media-dir <path>`. (Thanks [@96-LB](https://github.com/96-LB))
+- Added support for server-level user avatars. If a user has a custom avatar set on the server, it will be rendered instead of their main avatar.
+- CLI changes:
+  - Extended the `exportall` command with the `--data-package` option. You can use this option to provide the path to your personal data package (`package.zip` file), requested from Discord. When provided, the command will pull channels listed in the package instead of using the Discord API to query them. This can be particularly useful if you want to export DM channels that have been closed, as the personal data package should still contain their IDs.
+- HTML format changes:
+  - Added support for rendering group DM channel invites.
+  - Changed the primary font from `Whitney` to `gg sans` to match the new Discord design.
+  - Fixed an issue where the external font sometimes failed to load if the export was created with the "download assets" option enabled.
+  - Fixed an issue where `gifv` attachments were incorrectly treated as images instead of video files.
+
+## v2.38 (16-Feb-2023)
+
+- General changes:
+  - Added an option to disable markdown processing when exporting. You can use this to produce JSON or plain text exports without unwrapping mentions, custom emoji, and certain other special tokens. In GUI, this option can be found in the export dialog. In CLI, it's available as the `--markdown <true|false>` flag.
+  - Added support for different formatting options when rendering timestamps (i.e. the `f` in `<t:1234567890:f>`). As an exception, relative timestamps are formatted as regular timestamps since that makes more sense in a static export. Currently, all formatting options are rendered based on the `English (US)` locale, with the intent to make that more configurable in the future.
+  - Changed the default date format from `dd-MMM-yy hh:mm tt` to `MM/dd/yyyy h:mm tt` to match the date format used by Discord for message timestamps when the `English (US)` language is selected. This should make the default date format more consistent with other non-configurable date formats used by DiscordChatExporter. In the future, this setting will most likely be removed entirely in favor of a more flexible approach.
+  - Updated the usage guide with additional steps required to retrieve the user token.
+  - Fixed an issue where certain user mentions were incorrectly rendered as `@Unknown`.
+  - Fixed an issue where some embed images were rendered using their actual URLs instead of Discord proxy URLs.
+- GUI changes: 
+  - Added a text box for specifying the output path when exporting channels. It can be used to set an output path that uses template tokens, which previously required hacky workarounds. This text box can be left empty, in which case clicking on the "Export" button will open the file or folder picker dialog, matching the previous behavior.
+  - Added a notification when the application is updated to a new version, containing the changelog link.
+  - Moved the "reuse assets" option from the settings dialog to the export dialog.
+  - Replaced the lock icon in the token text box with a key icon, to better reflect the purpose of the input.
+  - Minor cosmetic improvements.
+- CLI changes:
+  - Changed the behavior of the `export` command when providing IDs of category channels. Now, instead of displaying an error, the command will export all channels contained within the corresponding categories.
+- HTML format changes: 
+  - Added proper support for more system notification messages.
+  - Added support for rendering server invites. Now, if the message contains an invite link, the export will show the server icon and include additional information, such as the name of the server and the target channel.
+  - Changed the preamble part of the export to show the channel icon when available, instead of the default Discord logo. This is only available for group DM channels. (Thanks [@CanePlayz](https://github.com/CanePlayz))
+  - Fixed an issue where some miscellaneous characters were incorrectly treated as emoji, which resulted in them being rendered as broken images. (Thanks [@CanePlayz](https://github.com/CanePlayz))
+  - Fixed an issue where messages triggered by app interactions were not rendered as replies.
+  - Fixed an issue where server cross-posts were not rendered correctly.
+- JSON format changes:
+  - Added an `iconUrl` field for the top-level `channel` object, which specifies the URL of the channel icon. This is only available for group DM channels.
+  - Added a `code` field for reactions, which specifies the code of the associated emoji. For standard Unicode emoji, this is equal to the emoji alias (e.g. `slightly_smiling_face`). For custom Discord emoji, this is equal to the emoji name (same as the already existing `name` field).
+  - Added an `interaction` field for messages, which contains information about the app interaction that triggered that response, if applicable.
+
+## v2.37.2 (27-Jan-2023)
+
+- Updated the links inside the application to point to the new documentation site. (Thanks [@CanePlayz](https://github.com/CanePlayz))
+- [CLI] Fixed an issue that there was no visual indication that an export task has failed before the whole process has completed.
+- Fixed an issue where the application sometimes crashed when it couldn't establish an HTTP connection to the target server.
+
+## v2.37.1 (10-Jan-2023)
+
+- [HTML] Fixed an issue where the export failed because it failed to resolve standard emoji image assets. Switched to a different CDN provider to mitigate this. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- [GUI] Fixed an application crash that happened when the user attempted to close the same dialog multiple times in a very short time.
+
+## v2.37 (08-Jan-2023)
+
+- Switched from .NET 6.0 to .NET 7.0. If running on Windows, the application should update all required prerequisites automatically. Alternatively, you can download the latest version of the runtime for your system [here](https://dotnet.microsoft.com/download/dotnet/7.0).
+- Updated rate limit handling to adjust automatically based on the response headers. This may result in exports taking longer than before on bot accounts, but it makes it less likely for Discord to throttle you. Exports with user accounts shouldn't be affected too much by this change.
+- Optimized snowflake parsing by removing unnecessary checks. (Thanks [@Kuba_Z2](https://github.com/KubaZ2))
+- [Docker] Optimized the Docker image size by using the Alpine base image and publishing a self-contained distribution. (Thanks [@Velithris](https://github.com/Zireael-N))
+- Fixed an issue where exporting a channel whose name ends with a dot would fail on Windows with default output path. The dots are now trimmed in file and directory names to match the behavior of Windows Explorer.
+
+## v2.36.4 (29-Oct-2022)
+
+- Changed all mentions of "media" in the context of "download media" or "reuse media" to "assets". CLI options will retain their existing names for backwards compatibility.
+- [HTML] Fixed an issue which prevented emoji used inside message content from being downloaded when "download assets" option is enabled. (Thanks [@Roberto Blázquez](https://github.com/xBaank))
+
+## v2.36.3 (21-Oct-2022)
+
+- [GUI] Fixed an issue where opening a dialog did not prevent user interactions with background UI elements using keyboard. This sometimes caused the application to crash in weird ways.
+- [Docker] Fixed an issue where DiscordChatExporter was running as root inside the container, making the exported files inaccessible to the host. (Thanks [@Benjamin Just](https://github.com/BamButz))
+
+## v2.36.2 (08-Oct-2022)
+
+- Removed the message content intent check because the heuristics turned out to be not reliable enough.
+- Fixed an issue where the runtime manifest included the wrong target runtime version. This resulted in the application failing to launch for some users when upgrading from earlier versions.
+
+## v2.36.1 (24-Sep-2022)
+
+- Added a check which will trigger an error if the provided bot account does not have the message content intent enabled. Note, however, that this check is based on heuristics which may result in false negatives.
+- Fixed an issue where certain transient HTTP errors were not retried.
+- Fixed an issue which caused the export process to fail with the `IndexOutOfRangeException` exception on certain automated messages.
+- Fixed an issue which caused the export process to fail on unrecognized embed types.
+
+## v2.36 (16-Sep-2022)
+
+- [HTML] Added support for rendering GIFV embeds. They will now render as videos that automatically play when you hover your mouse over them. (Thanks [@gan-of-culture](https://github.com/gan-of-culture))
+- [HTML] Added support for rendering system notification messages, such as when a user joins a server or when a messages gets pinned. Previously, such messages were rendered as regular text messages, but now they look similar to how they're presented in the Discord client. (Thanks [@gan-of-culture](https://github.com/gan-of-culture))
+- [CLI] Improved the wording of the error message that's shown when exporting multiple channels and the provided output path is ambiguous. It now mentions that you can resolve the ambiguity by adding a slash at the end of the path.
+
+## v2.35.2 (08-Sep-2022)
+
+- Updated usage guide to mention the need to enable "Message Content Intent" to use a bot as a medium for exporting messages.
+- [CLI] Fixed an issue where passing an existing directory as the output path failed when exporting multiple channels (for example, when running `exportdm`). An ambiguous output path will now always be treated as a directory path if that directory already exists. If it doesn't exist, it will be treated as a file path, matching the previous behavior.
+
+## v2.35.1 (26-Aug-2022)
+
+- Added `~` character as an alias for `-` when negating a message filter. This should make it easier to use negated filters from CLI where the dash character already has other meanings.
+- Extended retry logic to encompass all server-side errors from Discord API, instead of only `500 Internal Server Error`.
+- [CLI] Attempt to export multiple channels will now fail if provided with an output path that is neither a directory, nor a file name template. Previously, this resulted in all channels being exported to the same file, overwriting each other.
+- Fixed an issue where a text message filter didn't work if it started with a character that's also the first character in one of the named filters (e.g. `from` or `mentions`).
+- Fixed an issue where a text message filter didn't work correctly if it was enclosed in parentheses.
+- Fixed an issue where categories were displayed alongside regular channels in the channel list, both in GUI and in CLI (when using the `guild` command).
+- [CLI] Fixed an issue where an output path starting with a tilde on Linux was not expanded properly into a full path. (Thanks [@TSRBerry](https://github.com/TSRBerry))
+
+## v2.35 (02-Jul-2022)
+
+- Added support for exporting text chat in voice channels. These channels are now also displayed when browsing in the GUI and in the CLI when executing the `channels` command.
+- [GUI] Direct message channels are now sorted by the timestamp of their last message, similarly to how they appear in the Discord client.
+- [GUI] Removed artificial grouping of direct message channels into "Private" and "Group".
+- [CLI] Added runtime bootstrapper capabilities to the CLI flavor of DiscordChatExporter on Windows. Now, if you attempt to run the application without the required prerequisites installed, you will be provided with an option to install them automatically.
+- [CLI] Fixed outdated information in the usage guide. (Thanks [@Clint Herron](https://github.com/HanClinto))
+- [CLI] Added whitespace padding to the output of `guilds`, `channels`, and `dm` to make the tables look more uniform.
+- [HTML] Added hyperlinks to message timestamps, which allows you to quickly copy a link to a specific message in the export. (Thanks [@Philipp C. Heckel](https://github.com/binwiederhier))
+- [HTML] Added minification. Chat exports in HTML format are now 30-35% smaller than before.
+- [HTML] Added support for rendering embeds of Twitter posts that contain multiple images. Previously, this resulted in multiple separate embeds instead of one.
+- [HTML] Added support for rendering embeds of YouTube Shorts videos.
+- [HTML] Text content is now hidden if the message only contains a link to an image and nothing else. The link itself is resolved as an image embed.
+- [HTML] Fixed an issue where some emoji that included a zero-width-joiner rune were not rendered correctly due to a wrong Twemoji URL being generated. (Thanks [@Ethan](https://github.com/ethanndickson))
+- [HTML] Fixed an issue where replies to a message that contained a quote (i.e. `>`) were not rendered correctly.
+- [HTML] Fixed an issue where code blocks with language highlighting did not have the correct background color.
+- Added file name template token that resolves to the current date (`%d`). (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Updated the usage guide to replace the instructions for retrieving the user token with those that appear to work for more people.
+- Updated the usage guide to feature the TOS warning more prominently.
+- [Docker] Changed internal working directory from `/app/out` to `/out`. This was an unintended breaking change. Please update your volume binding configuration from `-v /path/on/machine:/app/out` to `-v /path/on/machine:/out`.
+
+## v2.34.1 (01-Jun-2022)
+
+- Improved retry policy to handle more transient errors. This should result in fewer errors exporting a channel due to timeout.
+- Added `has:pin` message filter. You can use it to limit exported messages to those that have been pinned. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Fixed an issue which caused the export to fail when processing stickers that have no name.
+
+## v2.34 (10-Apr-2022)
+
+- [HTML] Reworked layout to be more consistent with Discord.
+- [HTML] Changed user profile picture dimensions from `128x128` to `512x512`. (Thanks [@Chris Helder](https://github.com/TheDude53))
+- [HTML] Improved image scaling for Chromium-based browsers. This should result in higher quality images across the entire export.
+- [HTML] Hovering over messages will now show short timestamps on the left, indicating the time that the individual messages of the group were sent.
+- [HTML] Using "download media" option will now also download scripts, styles, fonts, and other similar resources used by the export.
+- [HTML] Image attachments will now use the provided description as alt text.
+- [HTML] Fixed a few layout inconsistencies related to embeds.
+- [GUI] Added a few clickable links to the usage guide to make the process of locating tokens easier.
+
+## v2.33.2 (07-Mar-2022)
+
+- Actually fixed it this time.
+
+## v2.33.1 (07-Mar-2022)
+
+- Fixed an issue where the application silently failed to run if the system didn't have .NET Runtime 6.0.2 installed. If you continue seeing this issue, please uninstall all existing .NET runtimes from your computer and then try running the application again.
+
+## v2.33 (06-Mar-2022)
+
+- Added messages informing about war in Ukraine and available ways to help.
+- Added support for rendering stickers in HTML and JSON. Lottie-based stickers currently cannot be displayed in HTML exports (see [#803](https://github.com/Tyrrrz/DiscordChatExporter/issues/803)).
+- Added a new `reaction:` message filter which can be used to check if someone reacted to a message with a specific emoji. You can either pass the emoji name (e.g. `reaction:LUL`) or its ID (e.g. `reaction:41771983429993937`).
+- [GUI] Added auto-detection for dark mode. If your system is configured to prefer dark mode in applications, DiscordChatExporter will use it by default instead of light mode.
+- Fixed an issue which caused the export process to crash when downloading media files with extremely long file extensions. (Thanks [@Tomlacko](https://github.com/Tomlacko))
+- Fixed an issue which caused the export process to crash on invalid mentions.
+- [GUI] Fixed an issue where the time pickers used to specify export ranges always displayed time in 12-hour format, instead of respecting the system locale.
+
+## v2.32 (27-Jan-2022)
+
+- Token kind (user or bot) is now detected automatically. Removed the button to switch token kind in GUI. Option `-b|--bot` in CLI is now deprecated and does nothing.
+- Updated user token extraction guide to reflect the fact that devtools are no longer accessible in the desktop version of Discord client. The recommended workaround is to open Discord in browser. (Thanks [@Dhananjay-JSR](https://github.com/Dhananjay-JSR))
+- Fixed an issue which caused an error when parsing invalid date timestamps. Such timestamps are now rendered as "Invalid date", similarly to how the Discord client does it.
+- Fixed an issue which caused an error when parsing certain embed fields.
+- Fixed an issue which caused an error when parsing a mention to a user that has no username.
+- [GUI] Minor visual fixes.
+
+## v2.31.1 (15-Dec-2021)
+
+- Fixed an issue which caused an error when parsing certain custom emoji reactions.
+- [GUI] Improved user interface.
+
+## v2.31 (06-Dec-2021)
+
+- Changed target runtime of the application (both GUI and CLI) from .NET 3.1 to .NET 6. Those using the GUI version will not need to take any action as the application should install the necessary prerequisites automatically. Those using the CLI version will need to download and install .NET 6 runtime manually [from here](https://dotnet.microsoft.com/download/dotnet/6.0) (look for ".NET Runtime 6.0.x" section on the right and choose the distribution appropriate for your system).
+- [HTML] Updated layout design to match Discord more closely. (Thanks [@Artem](https://github.com/Scarg))
+- [HTML] Fixed an issue where markdown inside channel topic was not rendered correctly. (Thanks [@Emily](https://github.com/emillly-b))
+- [HTML] Fixed an issue where the layout was broken for messages containing text in right-to-left languages. (Thanks [@Emily](https://github.com/emillly-b))
+- Fixed an issue where text filters weren't matching content inside of embeds.
+- [GUI] Fixed a multitude of issues related to the bootstrapper.
+
+## v2.30.1 (28-Aug-2021)
+
+- [HTML] Changed user avatars to render using higher resolution images. (Thanks [@Chris Helder](https://github.com/TheDude53))
+- Fixed an issue where `has:file` message filter was not recognized. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where a unix timestamp marker with an invalid offset crashed the export process.
+
+## v2.30 (08-Aug-2021)
+
+- [HTML] Added special casing for Spotify track embeds to render them directly using an embedded player.
+- [HTML] Added special casing for plain image embeds to render them like image attachments.
+- [HTML] Added tooltip text for unix timestamp markers which shows the full date represented by the timestamp, regardless of configured date format.
+- [HTML] Updated the fallback text shown when the referenced message could not be loaded to make it more explicit.
+- [HTML] Updated styling of quoted text in markdown to more closely resemble how it looks in Discord.
+- [HTML] Fixed an issue where some file formats were not correctly recognized as image or video attachments, which affected how they were rendered.
+- [HTML] Fixed an issue where formatting inside named links (e.g. `[**Bold link**](https://example.com)`) was not being parsed.
+- [HTML] Fixed an issue where inline embed fields were missing horizontal spacing between columns.
+- [HTML] Fixed other minor styling issues.
+
+## v2.29 (19-Jul-2021)
+
+- Added support for message filtering, which is accessible as an additional export parameter in the GUI and as the `--filter` option in the CLI. Message filters use a special syntax similar to Discord's search query syntax to allow specifying which messages should be included in the export. For example, you can limit the export to only include messages that contain image attachments (`has:image`) or messages from a certain user (`from:Tyrrrz`) or messages containing certain words (`hello world`), etc. You can also combine filters together (`hi mentions:Tyrrrz`, `from:Tyrrrz | from:96-LB`, `(mentions:Tyrrrz | from:Tyrrrz) has:image`) or negate them (`-has:link`). More thorough documentation coming soon. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Added support for rendering mentions of voice channels, in addition to text channels.
+- Added support for rendering unix timestamp markers. Currently, style markers are ignored and timestamps are always rendered with the format configured in settings (or provided via `--date-format` option).
+- Updated in-app instructions for obtaining a user token. (Thanks [@Yudi](https://github.com/Yudi) and [@virtuallyvlad](https://github.com/virtuallyvlad))
+- [HTML] Improved visual appearance of the reference symbol (Г-shaped line in replies) to make it more closely resemble Discord's styling.
+- [HTML] Added more specific fallback text used when rendering referenced messages that contain no text content but have attachments or embeds.
+- [HTML] Fixed an issue where a broken embed author icon occupied visual space, ruining the embed layout. (Thanks [@Cliff J.](https://github.com/CliffJameston))
+- [GUI] Improved handling for fatal errors that may occur when attempting to export a channel. These errors are now displayed in a popup, allowing the user to try again instead of having the application crash completely.
+- [CLI] Fixed an issue where an attempt to export a channel resulted in `NotSupportedException` when the default encoding was set to `UTF8`.
+- [CLI] Fixed an issue where providing an incorrectly formatted partition limit via `-p|--partition` option resulted in a non-descriptive and unhelpful error.
+- Improved "Requested resource does not exist" error message by including the ID of the requested resource.
+
+## v2.28 (19-Jun-2021)
+
+- [HTML] Added special casing for YouTube video embeds to render them directly using an embedded player. (Thanks [@quentinmay](https://github.com/quentinmay))
+- [HTML] Added support for rendering standard emoji by code. Such emoji may sometimes be found in messages sent by bots or through webhooks. (Thanks [@CanePlayz](https://github.com/CanePlayz) and [@Lucas LaBuff](https://github.com/96-LB))
+- [HTML] Changed tooltips on standard emoji to show emoji code instead of their raw string representations. (Thanks [@CanePlayz](https://github.com/CanePlayz) and [@Lucas LaBuff](https://github.com/96-LB))
+- [HTML] Added tooltips on individual messages to show when those messages were sent.
+- [HTML] Updated colors and minor styling elements to match Discord's new style direction after rebranding.
+- [HTML] Updated Twemoji URLs to use SVG image variants for better rendering quality.
+- [HTML] Changed user avatar URLs to include predetermined size query parameter for better rendering quality.
+- Changed embed rendering logic to prefer Discord-proxied URLs for external content, in order to avoid unnecessary HTTP requests to third parties.
+- Fixed an issue where exporting with media sometimes resulted in a crash due to lack of permissions to change file attributes. These errors are now ignored, which means that the creation, write, and access dates of downloaded files may sometimes not match the dates provided by Discord's CDN.
+- [HTML] Fixed styling issues when rendering embed footers.
+- [HTML] Fixed an issue where links didn't render properly inside referenced messages.
+- [HTML] Fixed an issue where standalone emoji were incorrectly enlarged inside referenced messages.
+- [HTML] Fixed an issue where clicking on a referenced message revealed spoilers inside of it.
+- [GUI] Fixed an issue where the list of missing components, reported by the prerequisite check at application startup, included Windows updates that were not applicable to the user's system due to the fact that other superseding updates have already been installed. This issue only affected users running DiscordChatExporter on Windows 7.
+- [GUI] Fixed a few other minor issues related to the prerequisite installation window.
+
+## v2.27.1 (08-Jun-2021)
+
+- [GUI] Application will now detect if the required .NET Runtime or any of its prerequisites are missing and prompt the user to download and install them automatically. **Experimental feature, please test it out and report any issues you may find!**
+- [CLI] Fixed an issue where the application crashed when exporting a channel that had square brackets as part of its name or category name. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+
+## v2.27 (24-Apr-2021)
+
+- Added partitioning by file size. You can now use values such as `10mb` to indicate a size-based cut off point, in addition to values like `10` to indicate a number of messages. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- [CLI] Improved formatting and progress reporting.
+- [CLI] Changed `export` command so that it can accept multiple channel IDs passed to `-c|--channel` option. This makes it possible to export multiple channels at once while benefiting from parallelization.
+- [JSON] Added `color` field to message author. This is a hex string that represents user's color, inherited from their roles. (Thanks [@rtm516](https://github.com/rtm516))
+- [JSON] Added `categoryId` field to the root. This represents the ID of the category channel that the currently exported channel belongs to. (Thanks [@rtm516](https://github.com/rtm516))
+- [JSON] Fixed an issue where user discriminator was written without leading zeroes. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- [JSON] Fixed an issue where the application sometimes crashed with an error saying `']' invalid without a matching open`, which was just a validation message that masked the actual error behind the failure. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where progress was not reported correctly if the channel didn't have any messages in the specified time range.
+
+## v2.26.1 (06-Feb-2021)
+
+- [CLI] Added support for file name templates, which allow you to dynamically generate output file names based on channel and guild metadata. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where the application sometimes crashed with `Invalid snowflake` message when exporting chat logs that contained invalid or outdated mentions. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+
+## v2.26 (29-Dec-2020)
+
+- [HTML] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [HTML] Improved styling of non-media attachments (regular files, i.e. not video, audio, or image). (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- [HTML] Improved initial export performance.
+- [JSON] Relaxed escaping rules for unicode characters. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [JSON] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [CLI] Added channel names to errors shown on failures when exporting multiple channels. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [CLI] Added support for passing message IDs (snowflakes) to `--after` and `--before` options. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Files downloaded by the "download referenced media" option now have their dates set according to the `Last-Modified` header provided by Discord CDN. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Fixed an issue where the application sometimes crashed with `NullReferenceException` when retrying a failed HTTP request.
+- Migrated to Discord API v8.
+
+## v2.25 (23-Nov-2020)

+- [CLI] Updated to [CliFx v1.5](https://github.com/Tyrrrz/CliFx), which brings some UX improvements.
+- [GUI] Added dark mode, which can be enabled in settings. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- [GUI] Improved the UX in a few minor places.
+- [JSON] Added `embed.color` property to the output. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added additional date formats: `unix` to write dates as a unix timestamp and `unixms` for the milliseconds version. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added retry policy for downloading media content. This is mostly a workaround for transient failures that sometimes may occur when downloading assets referenced from embeds. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added an option to reuse already downloaded media to avoid redundant network requests. It can be enabled in settings in GUI, or by passing `--reuse-media` in CLI. To facilitate this feature, the file name strategy has been changed as well -- now instead of relying on the original file name and adding `(n)` to the end in case of duplicates, a URL hash is injected in every file name. This also means that when the "reuse media" option is disabled, existing files inside the media directory may be overwritten. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))

+- Fixed an issue where self-contained export crashed occasionally. This usually happened when the server hosting the file did not serve the stream properly. Such files are now ignored after the first failed attempt.

 - [GUI] Improved the channel list by adding collapsible category groups. (Thanks [@CarJem Generations](https://github.com/CarJem))
 - [GUI] Improved exporting options by adding a set of controls that can be used to limit the date range of the export down to minutes. Previously it was only possible to configure the date range without the time component. (Thanks [@CarJem Generations](https://github.com/CarJem))
 - [HTML] Fixed an issue where the export didn't reflect changes in nicknames between messages sent by bots. This affected chat logs that contained interactions with the Tupperbox bot. (Thanks [@CarJem Generations](https://github.com/CarJem))
 - [CLI] Fixed an issue where the application crashed if there were two environment variables defined that had the same name but in different case.

-- Added a new option that enables self-contained exports for all output formats. You can turn it on in the export setup dialog in GUI or using the `--media` option in CLI. When using this, the application will additionally download any media content directly referenced from the exported file instead of linking back to Discord CDN. The files which are downloaded include: guild icons, user avatars, attachments, embedded images, reaction emojis. Note that only files which are actually referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using plain text export format. This option is not meant to enable complete offline viewing for HTML exports, but rather to make it easier to archive media content that may eventually get deleted from Discord servers. Also keep in mind that this option may make the export drastically slower and the total file size larger.

 - Changed "discordapp.com" to "discord.com" where applicable as Discord is migrating to a new domain. CDN will remain on "cdn.discordapp.com" for the foreseeable future.
 
-Note that all existing and current HTML exports will likely not render accurately because Discord enabled CORS for their font resources, which prevents them from loading locally. Please refer to [issue #322](https://github.com/Tyrrrz/DiscordChatExporter/issues/322) for discussion on this topic.

 - Added parallel exporting. This option allows you to export multiple channels faster by doing it in parallel. You can configure the parallel limit in settings (GUI) or with the `--parallel` option (CLI). Default value is `1`, which means there is no parallelization. Warning: be careful when using this option, as this will result in higher volume of concurrent HTTP requests sent to Discord, which might get you flagged. Use at your own risk.
 - [HTML] Added support for user colors. User names are now appropriately colored according to the assigned guild roles.
 - [HTML] Added support for nicknames. User names are replaced with nicknames where it's applicable. It's still possible to see the full user name by hovering your mouse over the nickname.

 - Added JSON export format. It's a structured data format which is easy to parse. If you're using DiscordChatExporter to export chat logs for further ingestion by another tool, this is most likely the format you will want to use.
 - [GUI] You can now quickly jump to a specific channel in a list. For example, if you want to jump to a channel named "General", you can simply press the 'g' key in the channel list view. You can also press 'g', 'e' and 'n' in quick succession which will jump to the next channel that starts with "gen". This mechanic is consistent with other Windows applications.
 - [CLI] Improved help text screen.

 - Fixed an issue where an empty file was produced when exporting a channel with no messages (for specified period). With the new behavior, no file will be created and instead a message will be shown to the user informing of the failure.
 - [HTML/TXT] Added message count to the bottom of the file. This number shows how many messages were exported as part of the current file. Prior to 2.16 this number was present along with the rest of the metadata at the top, then removed due to changes in the exporter, and now brought back at the end of the file instead.

+## v2.16 (08-Dec-2019)
 
 - Migrated from .NET Framework to .NET Core. To run this and future versions of DiscordChatExporter you will need [.NET Core runtime for desktop apps](https://dotnet.microsoft.com/download/dotnet-core/3.1/runtime) (for GUI/CLI version on Windows) or [.NET Core base runtime](https://dotnet.microsoft.com/download/dotnet-core/3.1) (for CLI version on Windows, Linux or macOS).
 - Reworked the exporter engine to render output using streaming data source. This means that only a very small portion of messages are cached in memory when exporting. In other words, you are only limited by storage space and not how much RAM you have, so you can now export terabytes of chat logs without hitting out of memory exceptions. I still recommend using partitions if you're exporting very large chat logs (250k+ messages) to HTML, unless you want your computer to catch fire when you try to open the export in browser.

This is a compromise I'm willing to take because detecting emojis in text is really hard to get right and not worth it at all.

 - [CSV] Replaced semicolons (;) with (,) as separators.
 
 Please note that CSV export is most likely not going to receive future updates and will remain only as an option for those who wish to use it for text analysis. In other words, it won't contain any of the rich media features like embeds. If you're currently using CSV as a structured output to feed into your program, JSON output will replace that in the future.
