+## 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 information when the pod is recreated.
+The CSIAddonsNode CR is deleted only when the CSI driver’s Deployment or DaemonSet is deleted.
