Thanks Wantok I was going to do that, but time isn't my friend right now.
The only thing I'd suggest is to break it down into sections. Take a look at the TE main page. Everything is broken down and easy to find.
You don't have to do it that way, but think of it more as player made documentation than a tutorial. Break it down into sections so if someone wants to see a specific topic, like "Exporting Shapes" or "Importing Shapes" they can do it from the main Object Editor page with a single click.
Also if it's done this way, user corrections or additions will be much more task specific.
