First, attach the door hinge or skirt holder thingy (don't know the specific name) to the baseplate (raise or lower it to where you need it first, though.). Then, attacth the skirts onto the hinge, and then click on the hinge you used and set the starting and ending points (I dont think ending point matters). After that just set it to a button and it's done.
Hope I didn't miss anything, was there anything you needed to know in specifics?
