REEF commit messages are very stylized. They are valid Markdown and contain:

  1. A first line referencing the JIRA and a short summary of what change was done. Focus on the change, not on the bug.
  2. A paragraph or more describing the change. Here, focus on the why?, not the what?
  3. A formal reference to the JIRA.
  4. A formal reference to the pull request.

Example
