 Thank you for considering contributing to the P4 Compiler Project (P4C)! Your contributions are valuable and help improve the project for everyone. Before getting started, please take a moment to review the following guidelines.
 
+## Contributing License
+The P4 organizations uses [DCO](https://en.wikipedia.org/wiki/Developer_Certificate_of_Origin) for contributions. Please take a look at our [guidelines](https://github.com/p4lang/governance/wiki/P4-DCO-Guidelines).
+
+To sign off the last commit quickly use the `git commit --amend --signoff` command. The failing check will also include instructions on how to sign off all commits in two steps (using `git rebase HEAD~$NUM_COMMITS --signoff`). https://github.com/src-d/guide/blob/master/developer-community/fix-DCO.md#dco-is-missing also provides helpful tips on fixing DCO inconveniences. Setting up a commit hook in the P4C repository will automate adding the DCO signoff.
