       for the change (usually before you start working on it).  Trivial changes like typos do not
       require a JIRA issue. Your pull request should address just this issue, without
       pulling in other changes.
 - [ ] Each commit in the pull request should have a meaningful subject line and body.
 - [ ] Format the pull request title like `[MNG-XXX] SUMMARY`,
       where you replace `MNG-XXX` and `SUMMARY` with the appropriate JIRA issue.
