✅ Why it is required

The Developer Certificate of Origin (DCO) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project. Here is the full text of the DCO.

Contributors sign-off that they adhere to these requirements by adding a Signed-off-by line to commit messages.

This is my commit message

Signed-off-by: Random Developer <randomdeveloper@example.com>

Git even has a -s command line option to append this automatically to your commit message:

$ git commit -s -m 'This is my commit message'
