Setup varies from model to model, with some models popping up in a single step and others requiring two or three steps. Be sure to read through the instructions before beginning.  The first step usually involves clearing the space in which the canopy will stand. Then you stand the frame upright and attach the cover to the frame. Pull the frame and cover outward, then lock each leg in place when it pulls taut. Adjust the legs to the desired height and secure the legs with stakes or weighted bags.
