 # renovate
 
-Renovate dependency update runner
+Self-hosted [Renovate](https://docs.renovatebot.com/) runner for the Lotus Guild Gitea instance.
+
+A Gitea Actions workflow (`.gitea/workflows/renovate.yml`) runs every Monday at 04:00 (and on demand) and
+checks the repositories listed in `renovate.json` for outdated dependencies. Renovate opens a pull request
+per update; patch updates and dev-dependency updates are squash-auto-merged, everything else waits for review.
+
+## Setup
+
+1. Create a Gitea access token for a bot/user with write access to the target repositories
+   (repository + issue/PR read-write).
+2. Store it as the repository secret `RENOVATE_TOKEN`.
+3. Add repositories to the `repositories` list in `renovate.json`.
