It didn't come with any instructions. We contacted customer support (multiple times) just to get a PDF of the instructions so we could build it, but it's been 2 weeks and still no response. Finally we decided to just try and build it without the instructions, and did 95% of it but a couple pieces are in the wrong spot, leaving a slight slant in the cabinet shelves that we might fix if we ever get the instructions. 
It also uses cam lock nuts for most of the connections, which aren't very durable.
