Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  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 [ARCHETYPE-XXX] SUMMARY,
  where you replace ARCHETYPE-XXX and SUMMARY with the appropriate JIRA issue.
• Also format the first line of the commit message like [ARCHETYPE-XXX] SUMMARY.
  Best practice is to use the JIRA issue title in both the pull request title and in the first line of the commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will be performed on your pull request automatically.

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.
