Trying to find more directions right now but love the table.  Eventually my wonderful partner who is skilled figured it out.  The table parts including the lower shelf come screwed together.  But the directions don't mention the temporary screws.  The temp bolts are not marked but are visible that they are holding the flat parts together for shipping.  It is a heavy, sturdy and wonderful table.  It has to stay out all winter, so I am pleased.  Oh yes, the tub for potting soil cannot have the lid on when it is in the slides of the table, so to keep water out, the bin would have to be removed and put on the lower shelf and covered.  Or.  The cover could be set on top of the table and anchored with something with weight.  Like for summer rain.
