No, I used a spade and boots to do the physical leveling. Then a few straight bits of wood with a big level to measure.
As I said it is a small/storage shed that I was relocating, so it would have been as much work to get a machine into the back as to do it by hand.
Probably also worth saying it went in an existing flower bed so digging was easier. Ymmv depending on location and size.
I don't have many pics as I was trying to fit it in at night and a couple of weekend nap times before my BiL came to stay who helped me move the shed.
My only other suggestions for a normal shed would be;
1) to allow for some extra round the edges for the rain run-off to fall onto as it will soak away better than grass and won't have dirty splash back.
2) have an extra "door matt" section at the front where the wear from foot traffic will be heaviest. Because it clicks together and can be easily cut you can do whatever shapes you want that would add to the cost of a concrete base.
