There's no introductory documentation (tutorial-style) on boo.
I would be willing to work on getting a tutorial together for boo.
(remember to check the wiki and make sure you're not duplicating material first, though. )
Is there any particular format or style guide I should currently adhere to, or should I just go ahead and start working on it and make it as simple as possible for now and add things later?
Its kind of ad-hoc and informal right now; you might want to stick with boo.codehaus.org/Coding+Conventions if you really need a style guide.
