How to add multiple authors to a commit

You can add multiple authors to a git commit, by adding one or more Co-authored-by trailers to the commit's message:

$ git commit -m "Refactor usability tests.
>
>
Co-authored-by: name <[email protected]>
Co-authored-by: another-name <[email protected]>"

Notes

• To correctly attribute a commit to a co-author, you must use the email associated with their GitHub account.
• If a person's email is private, you can use their GitHub-provided no-reply email.
• Leave one or preferably two empty lines before any Co-authored-by trailers.
