+Use the Control Panel
+===============
+
+The control panel is meant to be user friendly and safe explanatory.
+However some detail might be useful to know.
+
+Here is a picture of the control panel:

+   :alt: Control Panel without any configuration
+
+The control panel is divided in 3 parts:
+
+- The Navigation bar, where you can find the main pages, a Ros Bridge WebSocket status indicator and a WebSocket parameter button.
+- The main page, where you can find the configuration form and the control buttons.
+- The footer, where you can find the version number and the 3LawsRobotics website link and a link to the update pages.
+
+
+In order to use this control panel at its best, you need to configure the Ros Bridge WebSocket parameters.
+To do so, click on the WebSocket parameter button in the navigation bar and fill the form with the correct parameters.
+
+By default, the control panel is configured to connect to a Ros Bridge WebSocket running on the same machine, on the port 9090.
+More information on the Ros Bridge WebSocket can be found following this link: `Ros Bridge WebSocket <http://wiki.ros.org/rosbridge_suite>`_.
