Pre-PR checklist

• Ensure your source code changes
  • Build
  • Test
  • Lint
  • Have 100% test coverage
• Ensure good commit messages
  • Separate subject from body with a blank line
  • Limit the subject line to 60 characters
  • Use the imperative mood in the subject line
  • Do not end the subject line with a period
  • Wrap the body at 80 characters
  • Use the body to explain what and why vs. how
  • Use git rebase -i COMMIT_HASH to rework your commits if necessary
• Fill in PR description and reference an Issue for instance with #6
• Review the "Files changed" section of your PR
• "Think of the reviewer: your code needs to be reviewable and that should be a prime concern when writing your code, commits and PRs." (@camh-anz)
• Review a colleague's PR and add a link to the review in your own PR description
