 These libraries consist of the [PS3BT](PS3BT.cpp) and [PS3USB](PS3USB.cpp). These libraries allows you to use a Dualshock 3, Navigation or a Motion controller with the USB Host Shield both via Bluetooth and USB.
 
-In order to use your Playstation controller via Bluetooth you have to set the Bluetooth address of the dongle internally to your PS3 Controller. This can be achieved by plugging the controller in via USB and letting the library set it automatically.
+In order to use your Playstation controller via Bluetooth you have to set the Bluetooth address of the dongle internally to your PS3 Controller. This can be achieved by first plugging in the Bluetooth dongle and wait a few seconds. Now plug in the controller via USB and wait until the LEDs start to flash. The library has now written the Bluetooth address of the dongle to the PS3 controller.
 
-__Note:__ To obtain the address you have to plug in the Bluetooth dongle before connecting the controller, or alternatively you could set it in code like so: [PS3BT.ino#L20](examples/Bluetooth/PS3BT/PS3BT.ino#L20).
+Finally simply plug in the Bluetooth dongle again and press PS on the PS3 controller. After a few seconds it should be connected to the dongle and ready to use.
