We've chosen to use the Developer's Certificate of Origin (DCO) method that is employed by the Linux Kernel Project, which provides a simple way to contribute to the KhulnaSoft project.
The process is to certify the below DCO 1.1 text
Developer's Certificate of Origin 1.1

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), as indicated
in the file; 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.
