The instructions are pictures which not bad but there are 8 N pieces that support roof, 4 have 3 holes and 4 don’t. The pictures don’t tell you anything and there is no note that they need to be the center on sides between the 2 others and the ends. Had to tear apart and swap all 4 because roof holes didn’t match up. 3 hrs to swap. The actual structure is great and seems very durable.
