+Contributing to dumb-init
+========
+
+`dumb-init` is primarily developed by [Yelp](https://yelp.github.io/), but
+contributions are welcome from everyone!
+
+Code is reviewed using GitHub pull requests. To make a contribution, you should:
+
+1. Fork the GitHub repository
+2. Push code to a branch on your fork
+3. Create a pull request and wait for it to be reviewed
+
+We aim to have all dumb-init behavior covered by tests. If you make a change in
+behavior, please add a test to ensure it doesn't regress. We're also happy to
+help with suggestions on testing!
+
+
+## Releasing new versions
+
+`dumb-init` uses [semantic versioning](http://semver.org/). If you're making a
+contribution, please don't bump the version number yourself—we'll take care
+of that after merging!
+
+The process to release a new version is:
+
+1. Update the version in `VERSION` and run `make VERSION.h`
+2. Update the Debian changelog with `dch -v {new version}`.
+3. Update the two `wget` urls in the README to point to the new version.
+4. Commit the changes and tag the commit like `v1.0.0`.
+5. `git push --tags origin master`
+6. Wait for Travis to run, then find and download the binary and Debian
+   packages for all architectures; there will be links printed at the
+   end of the Travis output. Put these into your `dist` directory.
+7. Run `make release`
+8. Run `twine upload --skip-existing dist/*.tar.gz dist/*.whl` to upload the
+   new version to PyPI
+9. Upload the resulting Debian packages, binaries, and sha256sums file (all
+   inside the `dist` directory) to a new [GitHub
+   release](https://github.com/Yelp/dumb-init/releases)
