+## Pro License
+
+To enable Pro features (Slack/Teams/Email channels, CVE enrichment, incident management, maintenance windows, subscriber notifications, and more), set the `MAINTENANT_LICENSE_KEY` environment variable:
+
+```yaml
+services:
+  maintenant:
+    image: ghcr.io/kolapsis/maintenant-pro:latest
+    environment:
+      MAINTENANT_LICENSE_KEY: "your-license-key"
+```
+
+The license is verified periodically against the license server. If the server is temporarily unreachable, Pro features remain active from cache with a graceful degradation window.
+
+You can check the current license status via the API:
+
+```
+GET /api/v1/license/status
