+# This YAML file shows how to deploy the snapshot controller
+
+# The snapshot controller implements the control loop for CSI snapshot functionality.
+# It should be installed as part of the base Kubernetes distribution in an appropriate
+# namespace for components implementing base system functionality. For installing with
+# Vanilla Kubernetes, kube-system makes sense for the namespace.
