Hello Anna Marie,
When you set up the screen room for the first time. Keep the velcro strips to the outside (away from me). Not all of the panels get marked. So when I am showing a customer I hold up the panel with the valcro on the outside and look for the one with the zipper on the right first. Remember to remove the pull strap for the awning before you begin. It will slide out of its track once you slide it along towards the rear of the trailer. Then I will grasp the panel in the center, where the notch is, and beginning with your left hand slide it in to the end of the awning tube at the back of the trailer. You will see a small space for the screen room to slide into (this is also where your pull strap is removed from) begin with your left hand and slide it along the track until the zipper lines up in the center of the awning - there should be a light pencil mark - then take the second panel with the valcro on the outside and the zipper on the left and slide it into the track.
Then put your poles together one with holes and one without. The pointy end will go into the hole on the inside of the awning tube and the flat end will fit into a flat spot on the top of the trailer located just under the awning repeat for both sides. Remember these poles are spring loaded - like a tent pole - You may need a stool
