Put crate on the ground with pan on bottom. Unhook latch from the side.
Completely unfold one side and set it on the ground. The second side will not pull up easily if the first side is not unfolded thoroughly.
Pull up second side and align sides perpendicular to the ground.
Pull front panel up and out and when it is almost upright, pull up on top panel to let front panel to fit through. Pull panel outside of crate so the 2 top hooks are on the outside of top panel. Do it again for back panel.
