 The *gz_ros2_control* ``<plugin>`` tag also has the following optional child elements:
 
-* ``<parameters>``: YAML file with the configuration of the controllers
+* ``<parameters>``: A YAML file with the configuration of the controllers. This element can be given multiple times to load multiple files.
 * ``<hold_joints>``: if set to true (default), it will hold the joints' position if their interface was not claimed, e.g., the controller hasn't been activated yet.
+* ``<controller_manager_name>``: Set controller manager name (default: ``controller_manager``)
+
+Additionally, one can specify a namespace and remapping rules, which will be forwarded to the controller_manager and loaded controllers. Add the following ``<ros>`` section:
