Make a Tutorial for the full release

This custom map process is very difficult at first. It took me about two hours just to realize that I had to zoom in to be able to connect the land for it to save. So could somebody (doesn't even have to be a mod) add a tutorial to making it somewhere (either in-game or here in the forums) that describes in more depth what each tool does and how to use them. I'm sure there would be more people than just me who would be grateful.

Someone had already started writing a tutorial, and although still incomplete, it can be quite helpful for the beginners:
