Updating docs & changelog

[jlongster]

Hey all,

Can someone help update the docs to reflect the new API? We also need to start a changelog. If someone could also create a CHANGELOG.md file and describe the changes that have happened, that would be awesome.

I will release it once that is done. I have other work I need to do tonight, and I'll be at a work week all week this week so I won't have a whole lot of time.
