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.

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 account.

If a person chooses to keep their email address private, you should use their GitHub-provided no-reply email to protect their privacy. Otherwise, the co-author's email will be available to the public in the commit message. If you want to keep your email private, you can choose to use a GitHub-provided no-reply email for Git operations and ask other co-authors to list your no-reply email in commit trailers.

For more information, see "Setting your commit email address."

Tip: You can help a co-author find their preferred email address by sharing this information:

  • To find your GitHub-provided no-reply email, navigate to your email settings page under "Keep my email address private."

  • To find the email you used to configure Git on your computer, run git config user.email on the command line.

Creating co-authored commits using GitHub Desktop

You can use GitHub Desktop to create a commit with a co-author. For more information, see "Write a commit message and push your changes" and GitHub Desktop.

Add a co-author to the commit message

Creating co-authored commits on the command line

  1. 各 co-author (共同作者) の名前とメールアドレスを収集してください。メールアドレスをプライベートにしておきたい人がいる場合、そのプライバシーを保護するためにその人には GitHub が提供する no-reply メールを使わなければなりません。

  2. コミットメッセージと、変更についての短く意味のある説明を入力してください。コミットの説明のあとには、閉じる引用符の代わりに、2 つの空の行を追加してください。

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

*参考: コミットメッセージの入力にコマンドライン上のテキストエディタを使っているなら、コミットの説明とコミットのトレイラーの Co-authored-by: の間に 2 行が挟まれていることを確認してください。

  1. 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 GitHub the next time you push. For more information, see "Pushing changes to a remote repository."

Creating co-authored commits on GitHub

After you've made changes in a file using the web editor on GitHub, you can create a co-authored commit by adding a Co-authored-by: trailer to the commit's message.

  1. 各 co-author (共同作者) の名前とメールアドレスを収集してください。メールアドレスをプライベートにしておきたい人がいる場合、そのプライバシーを保護するためにその人には GitHub が提供する no-reply メールを使わなければなりません。

  2. After making your changes together, at the bottom of the page, type a short, meaningful commit message that describes the changes you made.

    Commit message for your change

  3. In the text box below your commit message, add Co-authored-by: name <name@example.com> with specific information for each co-author. If you're adding multiple co-authors, give each co-author their own line and Co-authored-by: commit trailer.
