Note: When you attempt to Log in with GitHub in the NetlfyCMS it won’t give you access. That's because your GitHub account must have push access to this repo, which you won't have.
The best thing for you to do is fork the repo and configure it with your own info. But, if you just want a quick look, send me an email (me@tylergaw.com) and I'll give you push access. (as long as the number of requests for access don't get too high)
