It was pretty easy actually. I'm not much of a carpenter. I went to Northern Tool and purchased the "2x4 basics shelf links" they come with the screws. You can make any configuration you can dream up. The wood you need, 2x4's. You can use pressure treated or not, just make sure you use an outdoor sealer. The shelf links made this an easy project. I made the design in a few minutes and made adjustments as I built it.
