 Prerequisites
 =============
 
-- Learn on to use ArduPilot first by following the relevant wiki for `Rover <https://ardupilot.org/rover/index.html>`__, `Copter <https://ardupilot.org/copter/index.html>`__ or `Plane <https://ardupilot.org/plane/index.html>`__. In particular make sure the vehicle works well in Manual and Autonomous modes like Guided and Auto before trying to use ROS.

 - Learn how to use ROS by reading the `beginner tutorials <http://wiki.ros.org/ROS/Tutorials>`__.  In the case of a problem with ROS, it is best to ask on ROS community forums first (or google your error). You will find many other tutorials about ROS like `Emlid <https://docs.emlid.com/navio2/common/dev/ros/>`__.
-- Install ROS Kinetic Kame on Ubuntu Linux (16.04). Those are default and LTS version of both ROS and Ubuntu.  ROS does not yet officially support Windows nor MAC.
