+## Runtime Risks
+
+You can track runtime risks through annotations. Add the annotation `github.com/runtime-risks`, with a comma-separated list of supported runtime risk values. Annotations are aggregated from the pod and its owner reference objects. 
+
+Currently supported runtime risks can be found in the [Create Deployment Record API docs](https://docs.github.com/en/rest/orgs/artifact-metadata?apiVersion=2022-11-28#create-an-artifact-deployment-record). Invalid runtime risk values will be ignored.

 ## Kubernetes Deployment
 
 A complete deployment manifest is provided in `deploy/manifest.yaml`
 which includes:
 
 - **Namespace**: `deployment-tracker`
 - **ServiceAccount**: Identity for the controller pod
-- **ClusterRole**: Minimal permissions (`get`, `list`, `watch` on pods)
+- **ClusterRole**: Minimal permissions (`get`, `list`, `watch` on pods; `get` on other supported objects)
 - **ClusterRoleBinding**: Binds the ServiceAccount to the ClusterRole
 - **Deployment**: Runs the controller with security hardening
