1. **GitHub App**: Set up a GitHub app for Buildbot to enable GitHub user
authentication on the Buildbot dashboard.
2. **OAuth Credentials**: After installing the app, generate OAuth credentials
and configure them in the buildbot-nix NixOS module.
and configure them in the buildbot-nix NixOS module. Set the callback url to
`https://<your-domain>/auth/login`.
3. **GitHub Token**: Obtain a GitHub token with `admin:repo_hook` and `repo`
