Before starting, you should do the following:

- Register an OAuth client. You should note down the client ID and possibly the client secret.
- Find the authorization server's authorization URL and token endpoint.
- Check if the authorization server supports PKCE. If it isn't specified, it likely doesn't support PKCE. Using PKCE is recommended if supported.

For a deep dive on everything auth, see the Auth Book. Feel free to ask questions on the Discord server linked in the book.
