The MIT License, Line by Line (2016)

Folks probably have a good idea what you mean by it, but you’re only going to save everyone—yourself included—time by copying the text of the standard MIT License form into your project. But while MIT-style license terms give others rights to build on and change the software, creating what the law calls “derivative works”, they don’t give the original author ownership of copyright in others’ contributions. While the Developer Certificate of Origin isn’t a license, it does provide lots of good evidence that those submitting code expected the project to distribute their code, and for others to use it under the kernel’s existing license terms.
