The instructions were for an indoor green, so I modified it for the outside.
I used treated 2x8's and 3/4" plywood instead of 2x4's and particle board. Its 8'x12', the grass is like an artifical turf. The cups were the hardest to install. I used outdoor carpet adhesive and liquid nails for the turf. I used PVC pipe and painted it yellow to put around the edge to keep the balls from falling off. It has natural downhill slant, to make it a little harder on the putts.
Here are a few pics (not in order).
