+  of the raft operator commands:
+
+  Joins a node to the raft cluster:
+
+      $ vault operator raft join https://127.0.0.1:8200
+
+  Returns the raft cluster configuration:
+
+      $ vault operator raft configuration
+
+  Removes a node from the raft cluster:
+
+      $ vault operator raft remove-peer
