+Handling Multiple Controller Managers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When dealing with multiple controller managers, you have two options for managing different robot descriptions:
+
+1. **Using Namespaces:** You can place both the ``robot_state_publisher`` and the ``controller_manager`` nodes into the same namespace.
+
+.. code-block:: python
+
+   control_node = Node(
+       package="controller_manager",
+       executable="ros2_control_node",
+       parameters=[robot_controllers],
+       output="both",
+       namespace="rrbot",
+   )
+   robot_state_pub_node = Node(
+       package="robot_state_publisher",
+       executable="robot_state_publisher",
+       output="both",
+       parameters=[robot_description],
+       namespace="rrbot",
+   )
+
+2. **Using Remappings:** You can use remappings to handle different robot descriptions. This involves relaying topics using the ``remappings`` tag, allowing you to specify custom topics for each controller manager.
+
+.. code-block:: python
+
+   control_node = Node(
+       package="controller_manager",
+       executable="ros2_control_node",
+       parameters=[robot_controllers],
+       output="both",
+       remappings=[('robot_description', '/rrbot/robot_description')]
+   )
+   robot_state_pub_node = Node(
+       package="robot_state_publisher",
+       executable="robot_state_publisher",
+       output="both",
+       parameters=[robot_description],
+       namespace="rrbot",
+   )
