+# Contributing to intentproof-sdk-python
+
+Thanks for your interest in contributing to the IntentProof Python SDK.
+
+## Developer Certificate of Origin (DCO)
+
+This repository accepts contributions under the
+[Developer Certificate of Origin 1.1](https://developercertificate.org/).
+We deliberately use DCO instead of a Contributor License Agreement
+for the Apache repositories so the contribution path stays
+frictionless.
+
+Every commit must carry a `Signed-off-by:` trailer matching the
+author email. The easiest way to do this is to pass `-s` to `git
+commit`:
+
+```bash
+git commit -s -m "..."
+```
+
+You can also retroactively sign off the last commit with:
+
+```bash
+git commit --amend --no-edit -s
+```
+
+Then force-push the amended branch:
+
+```bash
+git push --force-with-lease
+```
+
+Commits that do not include a valid `Signed-off-by` trailer will
+be rejected by CI.
