+    description: |
+      Revert a Filestore instance to the target snapshot.
+
+      This command can fail for the following reasons:
+        * The target snapshot does not exist.
+        * The active account does not have permission to revert the instance.
+        * The service tier of the instance does not support the operation.
+    examples: |
+      To revert an instance with the name ``my-instance'' that's located in
+      ``us-central1'' to the target snapshot named ``my-snapshot'' , run:
+
+        $ {command} my-instance --target-snapshot=my-snapshot --location=us-central1
