If you are looking to contribute to this project and want to open a GitHub pull request ("PR"), there are a few guidelines of what we are looking for in patches. Make sure you go through this document and ensure that your code proposal is aligned.
The sign-off is an added line at the end of the explanation for the commit, certifying that you wrote it or otherwise have the right to submit it as an open-source patch. By submitting a contribution, you agree to be bound by the terms of the DCO Version 1.1 and Apache License Version 2.0.
Signing off a commit certifies the below Developer's Certificate of Origin (DCO):

When committing your change, you can add the required line manually so that it looks like this:
Signed-off-by: John Doe <[email protected]>
Alternatively, configure your Git client with your name and email to use the -s flag when creating a commit:
$ git config --global user.name "John Doe"
$ git config --global user.email "[email protected]"
Creating a signed-off commit is then possible with -s or --signoff:
$ git commit -s -m "this is a commit message"
To double-check that the commit was signed-off, look at the log output:
$ git log -1
