+## Lifecycle of CSIAddonsNode CR
+
+The CSIAddonsNode custom resource (CR) is created by the sidecar that runs with the CSI driver. The owner of the CSIAddonsNode CR is the main owner of the sidecar pod, whether it's a DaemonSet or a Deployment. When the sidecar pod is deleted, the CSIAddonsNode CR is not removed; instead, it gets updated with new informations when the pod is recreated. The CSIAddonsNode CR is deleted only when the CSI driver’s Deployment or DaemonSet is deleted.
