+  short_description: View and debug OpenEBS storage resources
+  description: |
+    The openebs plugin provides a simplified interface to view
+    and debug different OpenEBS volumes and related storage resources.
+  caveats: |
+    * This plugin works with newer OpenEBS releases, where volumes are
+      provisioned by CSI.
+    * For resources that are not in default namespace, you must specify
+      -n/--namespace explicitly (the current namespace setting is not
+      yet used).
