If you aren't too good with codes then it will be confusing, it was for me.Just play around with the editor, if you want to edit your map Press F11, then press F8, and up at the top, it says Action, choose your action there such as Flatten, Smooth, Excavate, ect. And make your map. I have to recommend The Slopes because it has lots of hills and it's fun to play around with.
