How to Add GitHub Co-Authors and Multiple Authors?

In this guide, you will learn to add GitHub co-authors and multiple authors to your commits.

When you work on a project with other people, it’s important to give credit where credit is due. By adding co-authors to your commits, you can ensure that everyone who contributed to the project is properly recognized.

GitHub Co-authoring is an essential feature that enhances collaboration, transparency, and inclusivity in software development.

GitHub Co-authoring, also known as multiple authors or co-committing, is a collaborative feature that enables multiple individuals to receive proper recognition for their contributions within a single commit.

This feature is particularly useful when team members collaborate on a code base, as it helps maintain an accurate and comprehensive history of changes while acknowledging the specific contributions made by each person.

How to Add GitHub Co-Authors and Multiple Authors

To use GitHub Co-authoring, contributors add a special “Co-authored-by” trailer to their commit messages. This trailer includes the co-authors’ names and email addresses.

When the commit is pushed to GitHub, the platform recognizes these trailers and attributes the commit to all the specified co-authors in addition to the main author.

GitHub Co-Authors Commit Message Syntax

The syntax for adding co-authors to a commit message is as follows.

Co-authored-by: Co-Author Name <[email protected]>

For example:

Git init
Git add .
git commit -m “add: new feature

Co-authored-by: abc user <[email protected]>
Co-authored-by: cde user <[email protected]>"

You can add multiple co-authors by simply appending additional “Co-authored-by” lines to the commit message.

GitHub Co-authoring fosters transparency and promotes a more inclusive and collaborative development environment. It allows each contributor’s involvement to be clearly reflected in the project’s history, providing proper credit and recognition to everyone involved in shaping the code base.

Additionally, it facilitates the tracking of each contributor’s impact over time and helps in complying with licensing and attribution requirements when using open-source software.

By embracing GitHub Co-authoring, teams can better celebrate their collective efforts, strengthen collaboration, and foster a more welcoming and supportive atmosphere in their software development projects.

GitHub Co-Authors Importance

GitHub Co-authoring holds several key importance in the context of collaborative software development.

  1. Accurate Attribution: Co-authoring ensures that each individual’s contribution is properly recognized and attributed within the commit history. This helps maintain an accurate record of who worked on which parts of the codebase, which is crucial for transparency and giving credit where it’s due.
  2. Promotes Collaboration: Co-authoring fosters a sense of teamwork and encourages developers to work together on complex tasks. It allows multiple team members to work on the same feature simultaneously, making it easier to tackle large projects and reducing development time.
  3. Inclusivity and Diversity: By enabling multiple authors to be acknowledged in commits, co-authoring promotes a more inclusive development environment. It allows diverse teams with various skill sets and backgrounds to contribute to the code base and be recognized for their efforts.
  4. Compliance with Licensing: For open-source projects, proper attribution is essential to comply with licensing requirements. Co-authoring helps ensure that all contributors are acknowledged, making it easier to track and comply with various licensing agreements.
  5. Improved Code Review: With co-authoring, code reviews become more effective as reviewers can easily identify who made specific changes. This helps reviewers understand the context of the code modifications and provide more targeted feedback.
  6. Enhances Accountability: When multiple authors are associated with a commit, it fosters a sense of responsibility among team members. Developers are more likely to be diligent and careful with their contributions when their names are visible in the commit history.
  7. Historical Tracking: Co-authoring enables the tracking of individual contributions over time. This historical data can be valuable for performance evaluations, recognizing team members’ efforts, and identifying areas of expertise.
  8. Encourages Open Collaboration: Co-authoring encourages open collaboration and knowledge-sharing within the team. Developers can learn from each other’s code and build upon existing ideas, leading to higher code quality and innovation.


In conclusion, GitHub Co-authoring is an essential feature that enhances collaboration, transparency, and inclusivity in software development.

By giving proper credit to all contributors, it promotes a healthier and more productive team dynamic, resulting in better outcomes for projects of all sizes and complexities.
