+### Contributor compliance with Developer Certificate Of Origin (DCO)
+
+We require every contributor to certify that they are legally permitted to contribute to our project.
+A contributor expresses this by consciously signing their commits, and by this act expressing that
+they comply with the [Developer Certificate Of Origin](https://developercertificate.org/)
+
+A signed commit is a commit where the commit message contains the following content:
+
+```
+Signed-off-by: John Doe <jdoe@example.org>
+```
+
+This can be done by adding [`--signoff`](https://git-scm.com/docs/git-commit#Documentation/git-commit.txt---signoff) to your git command line.
