This is a pull request. It's used to ask for your code to be merged into the production version. In this case I'm requesting that the dev branch be merged into the gh-pages branch.

Notice that you can see all the code from each of our commits, this will all be merged to prod in a single action upon accepting this request. This is where code reviews take place primarily, via comments. 

Any new commits to the dev branch while this pull request is open will automatically be added to the the request as well.
