Update local master branch:

$ git checkout master
$ git pull upstream master

Create feature branch:
```
$ git checkout -b feature-x
```
Make one or more atomic commits, and ensure that each commit has a descriptive commit message. Commit messages should be line wrapped at 72 characters.
Run make test lint, and address any errors. Preferably, fix commits in place using git rebase or git commit --amend to make the changes easier to review.
Push:
```
$ git push origin feature-x
```
Open a pull request.
