I bet you didn’t, head over the Sven Killig’s site for full instructions.
You will need a micro USB cable (which I suppose you have), USB 2.0 One B Male to Two A Male Y-Cable (which is needed for extra USB charging power), USB 2.0 Hub, and HD USB Display Adaptor (if you want to display onto an external monitor).
