+excerpt: Learn how to add multiple authors to a git commit with this quick and easy tip.
+---
+
+You can add multiple authors to a git commit, by adding one or more `Co-authored-by` trailers to the commit's message:
+
+```sh
+$ git commit -m "Refactor usability tests.
+>
+>
+Co-authored-by: name <name@example.com>
+Co-authored-by: another-name <another-name@example.com>"
+```
+
+**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 preferrably two empty lines before any `Co-authored-by` trailers.
