I've volunteered to set up a documentation template, but have actually found a free to use one that's even better (with a no holds barred license on it as well) ->
http://css-tricks.com/examples/DocTemplate/
I'm doing my best to make sure there is information for the templates that I release (read me files and all that), and I actually have more time to design and stuff right now, so maybe I'll get started on that.
If I can find the link I was sent a while ago I'll share it here (Hoffie made something, but I can't quite remember where it ended up...).
This is the old post I was talking about, but the linked document is no longer at the address... -> http://www.mysidiaadoptables.com/forum/blog.php?b=67.
