+Contributions are welcome! Just clone this repository and install the dependencies:
+
+```bash
+git clone https://github.com/square/find-yarn-workspace-root.git
+cd find-yarn-workspace-root
+yarn
+```
+
+Note that you'll need `node` and `yarn` installed. Next, verify the tests all pass:
+
+```bash
+yarn test
+```
+

+
+## Releases
+
+Releases are handled by Travis CI once a build succeeds on `master`. To trigger a release, bump the version using `standard-version`:
+
+```bash
+$(yarn bin)/standard-version
+```
+
+That should update the CHANGELOG, bump the version in `package.json`, and create a git tag. Then, just `git push && git push --tags`.
