+The Matrix bot uses a normal account, so you can create it however you choose. If you already have an account made for the bot, skip step 1.
+
+### 1: Create a bot account
+
+Visit [app.element.io](https://app.element.io), and press "Create account".

+
+### 2: Add it to jfa-go
+
+Go to Settings and press the "+" button next to Matrix. If you can't see it, make sure messages/notifications are enabled, and matrix is disabled. **If you already have an access token, enable matrix and fill in the details yourself**.

+
+Fill in the:
+* Home server address (If you used the default on element.io, this will be `https://matrix.org`.
+* Username (`@<your username>:<your homeserver>`), for example, `@jfa-bot:matrix.org`.
+* Password
+
+then press submit. The app will restart and the page will refresh. Matrix should now be enabled.
+
+## Alternate method
+
+If adding your account through the wizard in jfa-go doesn't work, you can get the required access token yourself. 
+* Login to the account through element.io.
+* Click the dropdown next to your username on the top left and press "All settings".
+* Select "Help & About" on the right, and scroll down to the Advanced section. 
+* Click the dropdown next to "Access token", and copy the token.
+* In jfa-go, go to Settings > Matrix. Enable it, and paste the access token into the token box. Add your home server and user ID, then apply.
