  ### Notes
  
  - Make sure to open a PR from a **non-master** branch.
  - Sign off the commit using the `-s` flag when making a commit:
  
    ```sh
    git commit -s -m "..."
             # ^^ make sure to use this
    ```
  
  - Include `#{issue_number}` (e.g. `#123`) in the PR description when opening a PR.
