First, make sure you checkcompare the parts list before you start. Mine ended up coming without the window, so now I’m waiting for a replacement to complete the project. Instructions are pretty straightforward as long as you pay attention to detail. I made a mod on installing the doors as far as the lock goes by using small boltswith nuts instead of the wimpy phillips screws provided. 
Except for the window, I assembled this shed in about 4.5 hrs by myself. Nice little shed and is perfect for my intended use.
