Had no phone answer for help with assembly.   Step 1 was not explained whatsoever.  That step 1 was extremely difficult!   This Step 1 was key and should be explained.... no explanation was given.!    It was not easy and needed special pliers to install metal plugs for 1st board.   Steps 2 and beyond were trivial but had explanations. Do some kind of explanation for Step 1...shame on who wrote those directions.
