+## How to export with a bot token
+
+### Step 1 - Create an application
+
+You can create a new application or use an existing one. If you want to create a new one:
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Click on **New Application** in the top right corner
+3. Enter a name for your application and click **Create**
+
+### Step 2 - Invite the bot to your server
+
+The bot needs to be invited to the server you'd like to export from.
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Navigate to **General Information** on the left
+3. Copy the **Application ID**
+4. Open the following URL in your browser, replacing `YOUR_APP_ID` with the copied Client ID:
+
+<!-- Permission code 66560 corresponds to "View Channels" and "Read Message History" permissions.
+      User can uncheck these when adding the bot to their server. -->
+
+```
+https://discord.com/oauth2/authorize?scope=bot&permissions=66560&client_id=YOUR_APP_ID
+```
+
+### Step 3 - Ensure message content intent is enabled
+
+If this option is not enabled, the exported files will be empty.

 1. Go to [Discord developer portal](https://discord.com/developers/applications)
 2. Open your Application's settings
 3. Navigate to the **Bot** section on the left
-4. Under **Token** click **Copy**
+4. Scroll down to the **Privileged Gateway Intents** section
+5. Enable **Message Content Intent** by toggling the switch

-> **Warning**:
-> Your bot needs to have **Message Content Intent** enabled for it to be able to read messages!

+### Step 4 - Copy the bot token
+
+If you don't have a bot token yet or if you've lost it, follow these steps to reset it:
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Open your Application's settings
+3. Navigate to the **Bot** section on the left
+4. Under **Token** click **Reset Token**
+5. Click **Yes, do it!** and authenticate to confirm
+
+> **Tip**:
+> As the token is only shown once, make sure to store it in a safe place. If you lose the token, you will have to reset it again.
+
+> [!WARNING]
+> Resetting the token will invalidate the old one. Any integrations relying on the old token will cease to function until they are updated.
