I haven't really gotten the chance to read into the details. Most are great, just one comment below. Another thing, can you create a folder named docs, and just put this markdown file in there. It seems like there will be more documentation coming up soon, so I would like to have them all in one place. Thanks!

I think that your PR has multiple issues resulting from this commit 7b74560 . This reverts very important fixes. Please make sure to resolve this by restoring the deleted files and re-adding the important fixes

Hi @nathandloria, I think this PR is good! I have just added an mdl check into the Travis CI, so it would enforce markdown rules on documents in docs folder. Should anything fail (there is probably not, but just in case), just do a quick fix, I don't think it would be anything substantial. Thanks again!
