Pull Request Process

If you know that a particular person is subject matter expert in the area your PR affects, feel free to assign one or more reviewers when you create this PR, otherwise reviewers will be assigned for you.

Once the reviewer(s) accept the PR and the branch passes continuous integration in Bamboo, the PR is eligible for merge.

Otherwise, a reviewer can merge it for you.
