 Production always runs a specific version tag — `latest` is pushed for convenience/reference only (and always points at the most recently *released* build, not just the newest commit on `main`), `deploy.sh` never uses it.
 
+## GitHub Actions

+The GitHub repository is `whitehai11/anouma`; the workflows live in
+`.github/workflows/ci.yml` and `.github/workflows/release.yml`. In GitHub go to
+**Settings → Secrets and variables → Actions → Repository secrets** and create:
+
+| Secret | Required | Value |
+| --- | --- | --- |
+| `REGISTRY_USERNAME` | yes | Gitea Container-Registry username, normally `maro` |
+| `REGISTRY_PASSWORD` | yes | Gitea access token/password with permission to push/pull `git.maro.run/maro/anouma` |
+| `DEPLOY_HOST` | yes | Public IP or hostname of the production server |
+| `DEPLOY_PORT` | yes | SSH port, normally `22` |
+| `DEPLOY_USER` | yes | `anouma-deploy` |
+| `DEPLOY_SSH_KEY` | yes | Private key generated by `setup.sh` for the restricted deploy user |
+| `DEPLOY_HOST_KEY` | no | Complete SSH host-key line from a trusted `ssh-keyscan`; safer than first-connect trust |
+
+Es werden keine zusätzlichen GitHub-Variables benötigt; Registry und Image
+sind im Workflow fest auf `git.maro.run/maro/anouma` gesetzt. Runtime-Secrets
+wie `PAYLOAD_SECRET`, `MEETING_SESSION_SECRET`, `LIVEKIT_API_SECRET` und
+`DATABASE_URI` gehören ausschließlich in `/opt/anouma/.env` auf dem Server und
+nicht in GitHub Actions.
+
+Wichtig: Für Releases nur einen CI-Anbieter verwenden, damit nicht beide
+Systeme dasselbe Image parallel bauen oder deployen. Für dieses GitHub-Setup
+ist GitHub Actions die empfohlene Quelle; Gitea kann als Spiegel bestehen
+bleiben.

 Not a manual tool — it's invoked exclusively by Gitea Actions over SSH. What it does for `deploy.sh deploy vX.Y.Z`:
