+## Eclipse Contributor Agreement
+
+In order to be able to contribute to Eclipse Foundation projects you must
+electronically sign the [Eclipse Contributor Agreement (ECA)](https://www.eclipse.org/legal/ECA.php).
+
+The ECA provides the Eclipse Foundation with a permanent record that you agree
+that each of your contributions will comply with the commitments documented in
+the Developer Certificate of Origin (DCO). Having an ECA on file associated with
+the email address matching the "Author" field of your contribution's Git commits
+fulfills the DCO's requirement that you sign-off on your contributions.
+
+For more information, please see the [Eclipse Committer Handbook](https://www.eclipse.org/projects/handbook/#resources-commit)
