+# Renovate Bot
+
+The baseline only applies the basic settings for renovate, but does not include any credentials or platform configuration.
+
+Create a new secret to provide the necessary settings:
+
+```
+---
+apiVersion: v1
+kind: Secret
+metadata:
+  name: renovate-env
+  namespace: renovate
+type: Opaque
+stringData:
+  GITHUB_COM_TOKEN: 'your-github-token-here'
+  RENOVATE_PLATFORM: 'gitea'
+  RENOVATE_ENDPOINT: 'https://git.smsvc.net/'
+  RENOVATE_TOKEN: 'your-api-token-here'
+  LOG_LEVEL: info
+```
+
+You must set at least `RENOVATE_PLATFORM`, `RENOVATE_ENDPOINT` and `RENOVATE_TOKEN`.  
+You can set any configuration that can be set by environment variable (see References).
