Certainly a work in progress, but all links through the pages currently work.

There's a few pages that aren't anyone in the "course"

* customizing
* stashing
* Screencast
* amending
* distributed

I'd think distributed needs removed since it's empty and i would think this is more of an "extended learning" to a book (git-scm.com)

Amending i'll probably add front-matter, no idea where to add it though.

Screencast seems like a good thing to put after git-scm.md because it's an "additional resources" page.

Stashing also feels pretty essential that needs flushed out and written.

Customizing needs worked on, looks like a good "oh and heres how to add aliases!"
