+
+== Overview
+
+Managing the default storage class allows you to accomplish several different objectives:
+
+* Enforcing static provisioning by disabling dynamic provisioning.
+
+* When you have other preferred storage classes, preventing the storage operator from re-creating the initial default storage class.
+
+* Renaming, or otherwise changing, the default storage class
+
+To accomplish these objectives, you change the setting for the `spec.storageClassState` field in the `ClusterCSIDriver` object. The possible settings for this field are:
+
+* *Managed*: (Default) The Container Storage Interface (CSI) operator is actively managing its default storage class, so that most manual changes made by a cluster administrator to the default storage class are removed, and the default storage class is continuously re-created if you attempt to manually delete it.
+
+* *Unmanaged*: You can modify the default storage class. The CSI operator is not actively managing storage classes, so that it is not reconciling the default storage class it creates automatically. 
+
+* *Removed*: The CSI operators deletes the default storage class.
