+This documentation covers everything around the ROS (Robot Operating System) 2 driver packages for Universal Robots
+manipulators and the standalone Universal Robots Client Library (C++).
 
 With those packages it is possible to control a Universal Robots arm from an external application
 either directly using a C++ API (see :ref:`ur_client_library`) or using ROS 2 (see :ref:`ur_robot_driver`).
 
+This allows developing robot applications where one or more UR robots are a part of the complete
+application. Some key use cases are:
+
+- **External Monitoring and Control**: It allows you to monitor and control UR robots from an
+  external application. This can be useful for tasks like external vision systems for part
+  detection or external user interfaces to control robot programs.
+
+- **Ease of Use**: The *ur_client_library* has minimal external dependencies, primarily relying on standard
+  C++ libraries, making it straightforward to integrate and maintain.
+
+- **Integration with ROS / ROS 2**: The *ur_client_library* serves as the foundation for the ROS 2
+  driver, making it easier to integrate UR robots into ROS-based systems. ROS supports multiple
+  programming languages, primarily C++ and Python, making it easier to integrate with other
+  systems and tools. It also allows for communication between different nodes, enabling complex
+  robotic systems. The Universal Robots ROS packages offer everything from Visualization, over
+  simulation up to controlling a real robot bridging the great work of the ROS community with
+  Universal Robots manipulators.

 .. note::
    There is also builtin ROS 2 support for PolyScope X robots, see the `PolyScope X ROS 2 documentation <https://docs.universal-robots.com/polyscopex-ros2/v10.7/index.html>`_ and / or :ref:`ros2_controller_vs_driver` for details.
