 The Vitess cluster management daemon.
 
+### Synopsis
+
+vtctld provides web and gRPC interfaces to manage a single Vitess cluster.
+It is usually the first Vitess component to be started after a valid global topology service has been created.
+
+For the last several releases, vtctld has been transitioning to a newer gRPC service for well-typed cluster management requests.
+This is **required** to use programs such as vtadmin and vtctldclient, and The old API and service are deprecated and will be removed in a future release.
+To enable this newer service, include "grpc-vtctld" in the --service_map argument.
+This is demonstrated in the example usage below.
+
 ```
