A friendly reminder for new contributors:

What is DCO sign-off? Why is it required?

DCO stands for Developer's Certificate of Origin.

We require all commits to be DCO signed-off in case we need to track down and handle legal and/or technical issues.

To DCO sign-off your commits, you could run the git-commit command with the -s option or just add a line in your commit message in this format:

        Signed-off-by: yourFirstName yourLastName <yourEmail@example.org>

For more information, check out how PRs are checked for DCO sign-off: https://github.com/probot/dco#how-it-works .

Thank you very much.
