+## Gitea Actions
+
+Gitea Actions is enabled by setting:
+
+- `GITEA__actions__ENABLED=true`
+
+## Runner service
+
+The repository includes a dedicated Gitea Actions runner service named:
+
+- `gitea-runner`
+
+The runner uses Docker through the existing Docker socket proxy:
+
+- `DOCKER_HOST=tcp://docker-socket-proxy:2375`
+
+The runner intentionally **does not** mount:
+
+- `/var/run/docker.sock`
+
+## Registration token
+
+Generate a runner registration token from the Gitea UI:
+
+- Site Administration → Actions → Runners
+- or Repo → Settings → Actions → Runners
+
+Put the token in your env/secrets file:
+
+- `GITEA_RUNNER_REGISTRATION_TOKEN=...`
+
+## Start the runner
+
+- `./services-up.sh --profile gitea up -d gitea-runner`
+- or `./services-up.sh --profile all up -d gitea-runner`
+
+## Logs
+
+- `docker logs -f gitea-runner`
+
+## Labels
+
+Common workflow label:
+
+- `runs-on: ubuntu-latest`
+
+This should match the configured labels, for example:
+
+- `GITEA_RUNNER_LABELS=ubuntu-latest:docker://node:20-bookworm,...`
+
+## Security note
+
+The runner can control Docker through `docker-socket-proxy`. This is safer than mounting the raw Docker socket directly, but workflows still have meaningful control over Docker. Only trusted repositories/users should be allowed to run workflows on this runner.
