+### Codeberg support (via Gitea/Forgejo)
+
+Codeberg runs Forgejo, a fork of Gitea. dub-registry supports generic Gitea/Forgejo instances. To enable Codeberg support:
+
+- Set `gitea-url` to `https://codeberg.org/` in your `settings.json` (or use env var `GITEA_URL`).
+- (Optional) Set `gitea-auth` to a personal access token for higher API rate limits and to access private repositories (env var `GITEA_AUTH`).
+
+Note: currently only a single Gitea/Forgejo instance can be configured at a time.
