+# Contributing
+
+We value contributions to @KineticCafe/actions-dco—bug reports, feature
+requests, and code contributions.
+
+Before contributing patches, please read the [Licence.md](./Licence.md).
+
+@KineticCafe/actions-dco is governed under the Kinetic Commerce Open Source
+[Code of Conduct][].
+
+## Code Guidelines
+
+Our usual code contribution guidelines apply:
+
+- Code changes _will not_ be accepted without tests. The test suite is written
+  with [vitest][].
+- Match our coding style. We use Biome to assist with this.
+- Use a thoughtfully-named topic branch that contains your change. Rebase your
+  commits into logical chunks as necessary.
+- Use [quality commit messages][].
+- The version number must not be changed except as part of the release process.
+- Submit a pull request with your changes.
+- New or changed behaviours require new or updated documentation.
+
+A pull request will be accepted only if all code quality checks performed in
+GitHub Actions pass.
+
+@KineticCafe/actions-dco is compiled into a single file with `@vercel/ncc` for
+release. One of the status checks is that there are no changes during the
+packaging process. Ensure that you run `pnpm all` and commit any files in
+`dist/` once you are satisfied with your changes.
