+long-description: |
+  PersistentVolumes (PVs) provide an API that abstracts details of how storage is provided from how it is consumed.
+  PVs are used directly in scenarios where storage can be be created ahead of time (static provisioning).
+  For scenarios that require on-demand storage (dynamic provisioning), PersistentVolumeClaims (PVCs) are used instead.
