+# 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**:
+> 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.
+
+```console
+docker pull tyrrrz/discordchatexporter:stable
+```
+
+Note the `:stable` tag. DiscordChatExporter images are tagged according to the following patterns:
+
+- `stable` — latest stable version release. This tag is updated with each release of a new project version. Recommended for personal use.
+- `x.y.z` (e.g. `2.30.1`) — specific stable version release. This tag is pushed when the corresponding version is released and never updated thereafter. Recommended for use in automation scenarios.
+- `latest` — latest (potentially unstable) build. This tag is updated with each new commit to the `master` branch. Not recommended, unless you want to test a new feature that has not been released in a stable version yet.
+
+You can see all available tags [here](https://hub.docker.com/r/tyrrrz/discordchatexporter/tags?ordering=name).
+
+## Usage
+
+To run the CLI in Docker and render help text:
+
+```console
+docker run --rm tyrrrz/discordchatexporter:stable
+```
+
+To export a channel:
+
+```console
+docker run --rm -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+If you want colored output and real-time progress reporting, pass the `-it` (interactive + pseudo-terminal) option:
+
+```console
+docker run --rm -it -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+The `-v /path/on/machine:/out` option 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.
+
+> **Note**:
+> If you are running SELinux, you will need to add the `:z` option after `/out`, e.g.:
+>
+> ```console
+> 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 Bash
+- `-v $pwd.Path:/out` in PowerShell
+
+For more information, please refer to the [Dockerfile](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/DiscordChatExporter.Cli.dockerfile) and [Docker documentation](https://docs.docker.com/engine/reference/run).
+
+To get your Token and Channel IDs, please refer to [this page](Token-and-IDs.md).
+
+## Unix permissions issues
+
+This image was designed with a user running as uid:gid of 1000:1000.
+
+If your current user has different IDs, and you want to generate files directly editable for your user, you might want to run the container like this:
+
+```console
+mkdir data # or chown -R $(id -u):$(id -g) data
+docker run -it --rm -v $PWD/data:/out --user $(id -u):$(id -g) tyrrrz/discordchatexporter:stable export -t TOKEN -g CHANNELID
+```
+
+## Environment variables
+
+DiscordChatExpoter CLI accepts the `DISCORD_TOKEN` environment variable as a fallback for the `--token` option. You can set this variable 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](https://docs.docker.com/engine/reference/commandline/run/#set-environment-variables--e---env---env-file) for more information.

+# 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](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](Troubleshooting.md) section.
+
+The information presented on this page is valid for **all** platforms.
+
+## GUI or CLI?
+
+![GUI vs 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**](MacOS.md), [**Linux**](Linux.md) and [**Docker**](Docker.md) users can only use the CLI version.
+
+There are dedicated guides for each version:
+
+- [Using the GUI](Using-the-GUI.md)
+- [Using the CLI](Using-the-CLI.md)
+
+## 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
+
+```console
+from:Tyrrrz
+```
+
+- Filter by user (with discriminator)
+
+```console
+from:Tyrrrz#1234
+```
+
+- Filter by message content (allowed values: `link`, `embed`, `file`, `video`, `image`, `sound`)
+
+```console
+has:image
+```
+
+- Filter by mentioned user (same rules apply as with `from:` filter)
+
+```console
+mentions:Tyrrrz#1234
+```
+
+- Filter by contained text (has word "hello" and word "world" somewhere in the message text):
+
+```console
+hello world
+```
+
+- Filter by contained text (has the string "hello world" somewhere in the message text):
+
+```console
+"hello world"
+```
+
+- Combine multiple filters ('and'):
+
+```console
+from:Tyrrrz has:image
+```
+
+- Same thing but with an explicit operator:
+
+```console
+from:Tyrrrz & has:image
+```
+
+- Combine multiple filters ('or'):
+
+```console
+from:Tyrrrz | from:"96-LB"
+```
+
+- Combine multiple filters using groups:
+
+```console
+(from:Tyrrrz | from:"96-LB") has:image
+```
+
+- Negate a filter:
+
+```console
+-from:Tyrrrz | -has:image
+```
+
+- Negate a grouped filter:
+
+```console
+-(from:Tyrrrz has:image)
+```
+
+- Escape special characters (`-` is escaped below, so it's not parsed as negation operator):
+
+```console
+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:
+
+```console
+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:
+
+```console
+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 (`-`):
+
+```console
+DiscordChatExporter.Cli export [...] --filter ~from:Tyrrrz
+```

+# Scheduling exports with Cron
+
+Make sure you already have **DiscordChatExporter.CLI** and **.NET Core** properly installed ([instructions here](Linux.md)).
+
+## Creating the script
+
+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

+echo "$EXPORTFORMAT - Unknown export format"
+echo "Available export formats: plaintext, htmldark, htmllight, csv, json"
+echo "/\ CaSe-SeNsItIvE /\\"

+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](Token-and-IDs.md).
+- `channelhere` with a [Channel ID](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).
+
+---
+
+**Additional 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.

+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:

+- `tokenhere` with your [Token](Token-and-IDs.md)
+- `channelhere` with a [Channel ID](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 ✗

+
+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)](#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
+```

+# Scheduling exports on Windows
+
+We'll be using [DiscordChatExporter CLI](https://github.com/Tyrrrz/DiscordChatExporter/releases/latest), PowerShell, and Task Scheduler.
+
+## Creating the script
+
+1. Open a text editor such as Notepad and paste:
+
+```console
+# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs
+
+$TOKEN = "tokenhere"
+$CHANNEL = "channelhere"
+$EXEPATH = "exefolderhere"
+$FILENAME = "filenamehere"
+$EXPORTDIRECTORY = "dirhere"
+$EXPORTFORMAT = "formathere"
+# Available export formats: PlainText, HtmlDark, HtmlLight, Json, Csv
+
+cd $EXEPATH
+
+.\DiscordChatExporter.Cli.exe export -t $TOKEN -c $CHANNEL -f $EXPORTFORMAT -o "$FILENAME.tmp"
+
+$Date = Get-Date -Format "yyyy-MM-dd-HH-mm"
+
+If($EXPORTFORMAT -match "PlainText"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.txt"}
+ElseIf($EXPORTFORMAT -match "HtmlDark"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.html"}
+ElseIf($EXPORTFORMAT -match "HtmlLight"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.html"}
+ElseIf($EXPORTFORMAT -match "Json"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.json"}
+ElseIf($EXPORTFORMAT -match "Csv"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.csv"}
+exit
+```
+
+2. Replace:
+
+- `tokenhere` with your [Token](Token-and-IDs.md)
+- `channelhere` with a [Channel ID](Token-and-IDs.md)
+- `exefolderhere` with the .exe **directory's path** (e.g. C:\Users\User\Desktop\DiscordChatExporter)
+- `filenamehere` with a filename without spaces
+- `dirhere` with the export directory (e.g. C:\Users\User\Documents\Exports)
+- `formathere` with one of the available export formats
+
+Make sure not to delete the quotes (")
+
+3. Save the file as `filename.ps1`, not as `.txt`
+
+> **Note**: You can also modify the script to use other options, such as `include-threads` or switch to a different command, e. g. `exportguild`.
+
+## Export at Startup
+
+1. Press Windows + R, type `shell:startup` and press ENTER
+2. Paste `filename.ps1` or a shortcut into this folder
+
+## Scheduling with Task Scheduler
+
+Please note that your computer must be turned on for the export to happen.
+
+1. Press Windows + R, type `taskschd.msc` and press ENTER
+2. Select `Task Scheduler Library`, create a Basic Task, and follow the instructions on-screen
+

+# 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 questions
+
+### 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](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 export multiple formats at once?
+
+No, you can only export one format at a time.
+
+### 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.
+
+### Can DCE add new messages to an existing export?
+
+No.
+
+## First steps
+
+### How can I find my token?
+
+Check the following page: [Obtaining token](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](Dotnet.md), you might have downloaded the CLi flavor, try [downloading the GUI](Getting-started.md#gui-or-cli) instead.
+
+### How do I run DCE on macOS or Linux?
+
+Check the following pages:
+
+- [macOS usage instructions](MacOS.md)
+- [Linux usage instructions](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](Scheduling-Windows.md)
+- [macOS scheduling](Scheduling-MacOS.md)
+- [Linux scheduling](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](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](Dotnet.md)
+
+### I see messages in the export, but they have no content
+
+Your bot is missing the 'Message Content Intent'. Go to the [Discord Developer Portal](https://discord.com/developers/applications), navigate to the 'Bot' section and enable it.
+
+## CLI
+
+### How do I use the CLI?
+
+Check the following page:
+
+- [Using the CLI](Using-the-CLI.md)
+
+If you're using **Docker**, please refer to the [Docker Usage Instructions](Docker.md) instead.
+
+### Where can I find the 'Channel IDs'?
+
+Check the following page:
+
+- [Obtaining Channel IDs](Token-and-IDs.md)
+
+### I can't find Docker exported chats
+
+Check the following page:
+
+- [Docker usage instructions](Docker.md)
+
+### I can't export Direct Messages
+
+Make sure you're [copying the DM Channel ID](Token-and-IDs.md#how-to-get-a-direct-message-channel-id), not the person's user ID.

+# Using the CLI
+
+## Guide
+
+> **Note**:
+> Make sure you have [.NET Core installed](Dotnet.md) before attempting to run the commands below.
+> **Docker** users, please refer to the [Docker usage instructions](Docker.md).
+
+## Step 1
+
+After extracting the `.zip`, open Command Prompt, aka `cmd` (`Terminal` on **macOS** and **Linux**).
+
+## Step 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.
+![Copy path from Explorer](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
+![Mac info panel](https://camo.githubusercontent.com/3c51a904b0099c9f68a4797461d4a7914902fc04/68747470733a2f2f692e696d6775722e636f6d2f323975364e79782e706e67)
+
+You can also drag and drop the folder on **every platform**.
+![Drag and drop folder](https://i.imgur.com/sOpZQAb.gif)
+
+## Step 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.
+
+On **Windows**, type the following command in your terminal of choice, then press ENTER to run it. This will list all available subcommands and options.
+
+```console
+DiscordChatExporter.Cli.exe
+```
+
+On **macOS** and **Linux**, run the following instead:
+
+```console
+./DiscordChatExporter.Cli.sh
+```
+
+If either of the above approaches don't work for you, you can also run **DiscordChatExporter** directly like this, regardless of the platform:
+
+```console
+dotnet DiscordChatExporter.Cli.dll
+```
+
+> **Docker** users, please refer to the [Docker usage instructions](Docker.md).
+
+## CLI commands
+
+| Command                 | Description                                          |
+|-------------------------|------------------------------------------------------|
+| export                  | Exports a channel                                    |
+| exportdm                | Exports all direct message channels                  |
+| exportguild             | Exports all channels within the specified server     |
+| exportall               | Exports all accessible channels                      |
+| channels                | Outputs the list of channels in the given server     |
+| dm                      | Outputs the list of direct message channels          |
+| guilds                  | Outputs the list of accessible servers               |
+| guide                   | Explains how to obtain token, server, and channel ID |
+
+To use the commands, you'll need a token. For the instructions on how to get a token, please refer to [this page](Token-and-IDs.md), or run `dotnet DiscordChatExporter.Cli.dll guide`.
+
+To get help with a specific command, run:
+
+```console
+dotnet DiscordChatExporter.Cli.dll command --help
+```
+
+For example, to figure out how to use the `export` command, run:
+
+```console
+dotnet DiscordChatExporter.Cli.dll export --help
+```
+
+## Export a specific channel
+
+You can quickly export with DCE's default settings by using just `-t token` and `-c channelid`.
+
+```console
+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`.
+
+```console
+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:
+
+```console
+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 (").
+
+```console
+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 (").
+
+```console
+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 server and channel metadata.
+
+```console
+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` - server ID
+- `%G` - server 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.
+
+```console
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 -p 10
+```
+
+A 45 MB channel set to be partitioned every 20 MB will output 3 files.
+
+```console
+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.
+
+```console
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --media
+```
+
+#### Reusing 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.
+
+```console
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --media --reuse-media
+```
+
+#### Changing the media directory
+
+By default, the media directory is created alongside the exported chat. You can change this by using `--media-dir` and
+providing a path that ends with a slash. All of the exported media will be stored in this directory.
+
+```console
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --media --media-dir "C:\Discord Media"
+```
+
+#### Changing the date format
+
+You can customize how dates are formatted in the exported files by using `--locale` and inserting one of Discord's
+locales. The default locale is `en-US`.
+
+```console
+dotnet DiscordChatExporter.Cli.dll export -t "mfa.Ifrn" -c 53555 --locale "de-DE"
+```
+
+#### 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:
+
+```console
+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:
+
+```console
+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:
+
+```console
+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!
+More info about .NET date
+formats [here](https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings).
+
+### Export channels from a specific server
+
+To export all channels in a specific server, use the `exportguild` command and provide the server ID through the `-g|--guild` option:
+
+```console
+dotnet DiscordChatExporter.Cli.dll exportguild -t "mfa.Ifrn" -g 21814
+```
+
+#### Including threads
+
+By default, threads are not included in the export. You can change this behavior by using `--include-threads` and
+specifying which threads should be included. It has possible values of `none`, `active`, or `all`, indicating which
+threads should be included. To include both active and archived threads, use `--include-threads all`.
+
+```console
+dotnet DiscordChatExporter.Cli.dll exportguild -t "mfa.Ifrn" -g 21814 --include-threads all
+```
+
+#### Including voice channels
+
+By default, voice channels are included in the export. You can change this behavior by using `--include-vc` and
+specifying whether to include voice channels in the export. It has possible values of `true` or `false`, to exclude
+voice channels, use `--include-vc false`.
+
+```console
+dotnet DiscordChatExporter.Cli.dll exportguild -t "mfa.Ifrn" -g 21814 --include-vc false
+```
+
+### Export all channels
+
+To export all accessible channels, use the `exportall` command:
+
+```console
+dotnet DiscordChatExporter.Cli.dll exportall -t "mfa.Ifrn"
+```
+
+#### Excluding DMs
+
+To exclude DMs, add the `--include-dm false` option.
+
+```console
+dotnet DiscordChatExporter.Cli.dll exportall -t "mfa.Ifrn" --include-dm false
+```
+
+### List channels in a server
+
+To list the channels available in a specific server, use the `channels` command and provide the server ID through the `-g|--guild` option:
+
+```console
+dotnet DiscordChatExporter.Cli.dll channels -t "mfa.Ifrn" -g 21814
+```
+
+### List direct message channels
+
+To list all DM channels accessible to the current account, use the `dm` command:
+
+```console
+dotnet DiscordChatExporter.Cli.dll dm -t "mfa.Ifrn"
+```
+
+### List servers
+
+To list all servers accessible by the current account, use the `guilds` command:
+
+```console
+dotnet DiscordChatExporter.Cli.dll guilds -t "mfa.Ifrn" > C:\path\to\output.txt
+```

+
+> Video by [NoIntro Tutorials](https://youtube.com/channel/UCFezKSxdNKJe77-hYiuXu3Q).
+
+## Guide
+
+### Step 1
+
+After extracting the `.zip`, open `DiscordChatExporter.exe`
+
+### Step 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"/>
+
+### Step 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 ![Screenshot](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 ![Screenshot](https://i.imgur.com/dnTOlDa.png) button.
+
+<img src="https://i.imgur.com/JHMFRh2.png" height="400"/>
+
+### Step 4
+
+In this screen you can customize the following:
+
+- **Output path** - The folder where the exported chat(s) will be saved.
+
+- **Export format** - HTML (Dark), HTML (Light), TXT, CSV and JSON
+
+- **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.
+
+- **Partition limit** (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.
+
+- **Message Filter** (Optional) - Special notation for filtering the messages that get included in the export. See [Message filters](Message-filters.md) for more info.
+
+- **Format markdown** (Optional) - 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.
+
+- **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.
+
+- **Reuse assets** (Optional) - If this option is set, the export will reuse already downloaded assets to skip redundant requests. This option is only available when **Download assets** is enabled.
+
+- **Assets directory path** (Optional) - If this option is set, the export will use the specified directory to store assets from all exported channels in the same place.
+
+> **Note**:
+> You need to scroll down to see all available options.
+
+## Settings
+
+- **Auto-update**
+Perform automatic updates on every launch.
+Default: Enabled
+
+  > **Note**:
+  > Keep this option enabled to receive the latest features and bug fixes!
+
+- **Dark mode**
+Use darker colors in the UI (User Interface).
+Default: Disabled
+
+- **Persist token**
+Persist last used token between sessions.
+Default: Enabled
+
+- **Show threads**
+Controls whether threads are shown in the channel list.
+Default: none
+
+- **Locale**
+Customize how dates are formatted in the exported files.
+
+- **Date format**
+Customize how dates are formatted in the exported files in the settings menu ().
+
+- **Parallel limit**
+The number of channels that will be exported at the same time.
+Default: 1
+
+- **Normalize to UTC**
+Convert all dates to UTC before exporting.
+
+  > **Note**:
+  > Try to keep this number low so that your account doesn't get flagged.
