It's dead easy to erect and use. Lay out the three "poles" The two of the same size are the ones that fit from the roof corners to the floor; the other goes around the awning. Helps to have one person pushing the poles into the sleeves from the bottom while another person guides the poles through. As with other awnings, zip the doors before pegging out. Start at the 'van and make sure you peg the awning as close to the van body as possible. Then peg the other end of the awning near the van again.
When dismantling, do not pull the poles out of their sleeves - feed/push through from the top.
