 # Discord Echobot
 
-A Node.js Discord Self-Bot to Copy Messages From One Channel to Another
+The purpose of this bot is to allow you to copy messages from one Discord channel to another Discord channel, even if you don't have permission to add a bot account to the guild you are copying from.
+
+This is done by turning your own Discord account into a bot -- copied messages are sent by _you_, not a bot.

+## Finding your Token
+
+This Discord bot is called a "self-bot," meaning it runs as your personal Discord account rather than a separate bot account.
+
+In order for this to work, you need to provide your Discord token in the `config.json` file. To find this token, follow these steps:
+
+1. Open the Discord client on your computer.
+2. Push `Ctrl + Shift + I` to open the dev tools (may be different on non-windows operating systems).
+3. Go to the `Application` tab (may be hidden under the `>>` arrows).
+4. Click on "Local Storage -> https://discordapp.com".
+5. Find the `token` key, usually at the bottom, and copy the value.
+
+The token will now be on your clipboard and can be pasted into the config. Make sure there is only one set of quotation marks.
+
+## Finding Channel IDs
+
+Redirect sources and destinations use Channel IDs, which look like large numbers. To find these, follow these steps:
+
+1. Open the Discord client.
+2. Go to User Settings.
+3. Go to Appearance.
+4. Scroll to the bottom and enable Developer Mode.
+5. Close User Settings.
+6. Right click on any channel (only text channels are supported, not voice) and select `Copy ID`.
+
+The ID will now be on your clipboard and can be pasted into the config.
