 # ROS2 Example
 
 This example is a basic ROS2 implementation with NiceGUI.
-It starts up a virtual joystick on a local webpage (127.0.0.1:8000), that publishes messages on the /turtle1/twist topic for an instance of turtlesim_node to be controlled.

 ROS2 and NiceGUI are fully functional in this example, changes to the code will trigger a restart of the full ROS2 Node.
