1. locate your BD installation. For Windows it is usually in `%localappdata%\Discord\app-0.0.305\resources\app\betterdiscord`.
2. Open config.json in a text editor (n++, notepad, etc).
3. Change the line `"branch": "master",` to `"branch": "development",`.
4. (optional) Change `"minified": false,` to `"minified": true,` to stay on the bleeding edge (sometimes I forget to update the minified version).
5. Fully restart your Discord client.
6. You can verify it worked by seeing the revamped plugins and themes pages as well as custom css. You can also see if the version in settings is 1.0.0+
