Hello! The name of the branch with this Pull Request is not of the add-USERNAME pattern so I'm skipping reviewing it for the Git-it challenges.
If you are completing the Git-it challenges, you'll need to close this Pull Request, rename your branch, push it to your fork of Patchwork on GitHub and then start a new Pull Request. Here's how to rename a branch and push it to GitHub from terminal:

$ git branch -m add-USERNAME
$ git push origin add-USERNAME
