Pretty straight forward. Put fasteners (nails or screws) where the pilot holes are and squeeze the handle where handle holes are. I used nails for everything except the upper side rails, where I used screws. If I ever need to replace or adjust the rail, it could be removed fairly simply. Nails were used because I had a lot of them from dismantling pallets and didn't want to waste them. Think green!
The rebar was somewhat difficult to fit through the holes. Some pliers to help twist and a hammer to tap will makes this part of the process much easier.
