First I want to meet the Mother and Daughter who put this shed together in 2 -3 hours-  I would hire them---I had myself and two other experienced craftsmen as I am also experienced--it took a day and a half one main reason being most holes did not line up properly  and I was on perfectly level concrete  It is a nice shed but lots of work  and bending- kneeling  No written explanations---all drawings which were hard to read the small numbers   Took at least 45 minutes to an hour to check all parts to be sure all was there  Some damage to some pieces but managed to salvage them  Hope this is helpful but don'y be afraid to put one up  just a little more work and time then they say
