 # renovate-bot
 
-Central Renovate configuration — reusable Gitea Actions workflow + global config
\ No newline at end of file
+Central Renovate configuration for all repos on scm.cabillot.eu.
+
+## How it works
+
+This repo (public) contains:
+- `config.json` — global Renovate config (no secrets, only placeholders resolved at runtime)
+- `.gitea/workflows/renovate.yaml` — reusable Gitea Actions workflow (`workflow_call`)
+
+Being public allows the Gitea Actions runner to clone this repo for reusable
+workflow calls. No secrets are stored here — they come from org-level secrets
+on the calling repo's org.
+
+## Adopting Renovate in a repo
+
+Add this workflow file to your repo at `.gitea/workflows/renovate.yaml`:
+
+```yaml
+name: Renovate
+
+on:
+  schedule:
+    - cron: '0 0 */2 * *'
+  push:
+    branches:
+      - main
+  workflow_dispatch:
+
+jobs:
+  renovate:
+    uses: perso/renovate-bot/.gitea/workflows/renovate.yaml@main
+    secrets: inherit
+```
+
+That's it. Renovate will:
+- Scan every 2 days for dependency updates
+- Re-run on every push to `main` (after merges) to rebase stale PRs
+- Be triggerable manually via `workflow_dispatch` (UI or API)
+
+## Per-repo overrides
+
+Add a `renovate.json` at the root of your repo. It will be merged with the
+global config.
+
+## Required secrets
+
+These must be set as **org-level secrets** in the Gitea org of the consumer repo:
+
+| Secret | Purpose |
+|--------|---------|
+| `RENOVATE_TOKEN` | Gitea API token for the renovate bot |
+| `RENOVATE_GITHUB_TOKEN` | GitHub token for GitHub-hosted dependencies |
+| `RENOVATE_SSH_KEY` | SSH private key for git operations (optional) |
