Remove all the staples and remove one side of the casing, leaving the door in the frame. Remove the fastener that prevents the door from opening out of the frame. Slide the frame and door into the door opening, starting at the base, tilting the door into place. Once the door frame is in place, open the door and secure it in the open position with some wood shims. Starting at the base, tilt the door and frame up into place.
