+This example demonstrates a movement for an ABB robot using the COMPAS RRC 
+python API from Grasshopper.
+
+To run the example:
+
+* Run ``python -m compas_rhino.install`` to install compas packages to Rhino and 
+  Grasshopper. See `COMPAS - Rhino (Windows and Mac) <https://compas.dev/compas/latest/gettingstarted/rhino.html>`_
+  for more details.
+* Start the robot where the RRC driver is installed.
+* Start ROS driver using Docker (see example ``docker-compose.yml`` below).
+* Open `grasshopper-script.ghx <./grasshopper-script.ghx>`_ in Grasshopper.
+
+For more details, check the `COMPAS RRC Start <https://github.com/compas-rrc/compas_rrc_start>`_ repository.
