+# MaxCtrl
+
+MaxCtrl is a command line administrative client for MaxScale which uses
+the MaxScale REST API for communication. It is intended to be the
+replacement software for the legacy MaxAdmin command line client.
+
+By default, the MaxScale REST API listens on port 8989 on the local host. The
+default credentials for the REST API are \`admin:mariadb\`. The users used by the
+REST API are the same that are used by the MaxAdmin network interface. This
+means that any users created for the MaxAdmin network interface should work with
+the MaxScale REST API and MaxCtrl.
+
+For more information about the MaxScale REST API, refer to the
+[REST API documentation](../REST-API/API.md) and the
+[Configuration Guide](../Getting-Started/Configuration-Guide.md).
