Creating a commit with multiple authors

You can attribute a commit to more than one author by adding one or more Co-authored-by trailers to the commit's message. Co-authored commits are visible on GitHub Enterprise and can be included in the profile contributions graph and the repository's statistics.

Required co-author information

Before you can add a co-author to a commit, you must know the appropriate email to use for each co-author. For the co-author's commit to count as a contribution, you must use the email associated with their GitHub Enterprise account.

Creating co-authored commits on the command line

  1. Collect the name and email address for each co-author.

  2. Type your commit message and a short, meaningful description of your changes. After your commit description, instead of a closing quotation, add two empty lines.

    $ git commit -m "Refactor usability tests.
    >
    >

    Tip: If you're using a text editor on the command line to type your commit message, ensure there are two lines between the end of your commit description and the Co-authored-by: commit trailer.

  3. On the next line of the commit message, type Co-authored-by: name <name@example.com> with specific information for each co-author. After the co-author information, add a closing quotation mark.

    If you're adding multiple co-authors, give each co-author their own line and Co-authored-by: commit trailer.

    $ git commit -m "Refactor usability tests.
    >
    >
    Co-authored-by: name <name@example.com>
    Co-authored-by: another-name <another-name@example.com>"

The new commit and message will appear on your GitHub Enterprise Server instance the next time you push. For more information, see "Pushing to a remote."
