I put the upper doors back on the frames. Attaching them was fairly easy. I set all my hinges two inches inside the edge of the door. I laid the hinges on the door, marked the holes, drilled pilot holes for the screws, then attached the hinges to the door. Then I held the door up to the frame, made sure it was level, marked the hinge holes on the frame, drilled pilot holes then attached the door to the frame.
