The shed is well built and square...all the panels and boards are connected securely and when screwed together there are no gaps. 
The wood is light and soft which can be a benefit and a detriment. The lightweight allows for easy portability, but also may not withstand heavy to extra heavy loads. 
Assembly can be accomplished with one person, but with 2, it would be much easier. 
Be sure to account for all the pieces before discarding the box. Some pieces are light enough that they can be unnoticeable when lifting an 'empty' box. 
All the holes in each board and panel are pre-drilled. Pay attention to these holes as they will help discern right from left and front to back. 
*note...the small wooden piece that is screwed into the very top center of the rear wall...notice the angle of the one side...the angled side needs to follow the angle if the side walls so that the roofs sets on it squarely.
