+## Contributing
+
+If you'd like to contribute to Jasper, we've created a Contributing Guide, available [here](https://github.com/jasperproject/jasper-client/blob/master/CONTRIBUTING.md). It outlines the philosophies to preserve, tests to run, and more. If you're looking for potential features to build, we've included some recommendations there as well.
+
+We highly recommend reading through this guide before writing any code. Thanks in advance for any and all work you contribute to Jasper!
