+# Drone
+
+For a very simple drone demo, we're going to use Cylon to make an ARDrone take
+off, hover, and land. Before you get started, make sure you have the
+`cylon-ardrone` module installed.
+
+First, we need to load up Cylon.
+
+    Cylon = require '../..'
+
+And now that we have that taken care of, we can define our robot.
+
+    Cylon.robot
+
+Our robot will communicate with an ARDrone over an IP address, and controls the
+drone using a device we're going to call "drone":
+
+      connection: { name: 'ardrone', adaptor: 'ardrone', port: '192.168.1.1' }
+      device: { name: 'drone', driver: 'ardrone' }
+
+The work for this robot is pretty straightforward. It's going to take off, and
+then land after ten seconds. Five seconds later, after it's safely on the
+ground, it will fully stop.
+
+      work: (my) ->
+        my.drone.takeoff()
+        after 10.seconds(), -> my.drone.land()
+        after 15.seconds(), -> my.drone.stop()
+
+Simple as can be. And now that we've got all that set up, we can get started!
+
+    .start()
