The assembly directions were adequate. My wife helped install walls. My weight was barely enough to pope them into the floor slots. The door support floor inserts can be installed after the walls are in place. A couple of the ceiling panels took a lot of finessing to get all the screws started.  After installation was complete, the doors would not close properly. Alignment was almost perfect. I called and was sent replacement metal edge pieces for the doors.  Installed an electric outlet and light on the inside and a light on the outside with switches on the inside.  I am happy with my new shed.
