What is a one-sentence summary of the following article?
Typically, screen doors are made from a lightweight aluminum frame and fiberglass screen material. To remove the door, lift it upward while pulling the bottom away from the track along the bottom. Then, place the door on a flat surface. If you have a door handle in the way of your screen, remove the screws with a flathead screwdriver to take it off. The door should easily come off with moderate force. Not all door styles will have a door handle overlapping the screen. If your screen door is on hinges, tap the hinge pins with a screwdriver to remove them and slide the door upward from the hinges. The splines are pieces of narrow rubber tubing that keep the screen secure around the door frame. There is a separate piece of spline for each side of the screen. Use an awl or your screwdriver to pry up the spline at the corner of the frame. Then, grab the spline and gently pull it upward. Do this for all 4 sides of your door frame. Be careful when removing the splines. If they are still in good shape, you can reuse them. If you pierce the splines or damage them, throw them away and get new splines that have the same diameter as the old ones. Once the splines are removed, the screen is no longer attached to the door. At this point, you can simply lift it off of the door frame. Fold it up, roll it up, or bunch it up before you throw it away.

Summary:
Remove the door from the frame and take off the door handle. Pull the splines out of the door frame groove with steady, firm pressure. Remove the old screen material from your door frame.
