+The coreboot project uses the Developer Certificate of Origin as its
+policy of accepting contributions. As such, a submitter bears the burden
+that they have all necessary rights to submit their contribution to the
+project under the project's licenses as appropriate. Violations of third
+party rights will lead to the code's removal or replacement as suitable
+to bring the project back into compliance.
+
+This applies no matter under which circumstances a contribution has been
+created: legal frameworks, work contracts, Generative Artificial
+Intelligence ("AI") tooling, or other aspects that may affect the
+ownership and copyright status of a contribution are outside the
+project's control.
+
+See the [Sign-off procedure] for more information.
