Developer Certificate of Origin
To minimize barriers for developers contributing code and to strengthen free collaboration within the community, this project uses a mechanism known as the DCO (Developer's Certificate of Origin) to manage the contribution process.
The DCO lets developers easily certify that they wrote the code or documentation themselves and that they have the right to submit it to the project.
The original text of the DCO: https://developercertificate.org

Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or
(b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license); or
(c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.
(d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
Signing the DCO
If you have set user.name and user.email in your git configuration, you can sign your commits automatically with git commit -sS, which combines the following two flags.
-s:
Appends a Signed-off-by line to the commit message, indicating that the committer has signed the Developer Certificate of Origin.
-S (GPG Sign):
Signs the commit with GPG, ensuring the authenticity and trustworthiness of the commit source.
An example of a signed-off commit is shown below.
Signed-off-by: Some Developer somedev@example.com
If more than one person is involved, sign-offs from all contributors are required.
Signed-off-by: Some Developer somedev@example.com
Signed-off-by: Another Developer anotherdev@example.com
