 ## Installation
 
-On your ROS robot, the `rosbridge_suite` from [Robot Web Tools](http://robotwebtools.org) needs to run. So to use the control center with your existing project, call `roslaunch rosbridge_server rosbridge_websocket.launch` to launch the websocket server. The control center runs on any computer (in particular without ROS...) in the same network. Open the ROS Control Center at [https://pantor.github.io/ros-control-center](https://pantor.github.io/ros-control-center). In the settings tab, you need to enter the IP address and port of your robot. Open the `Control` tab and reload.
