For contributors who are interested in getting more involved in SIG-Storage, please review the [CONTRIBUTING Guide](https://github.com/kubernetes/community/blob/master/sig-storage/CONTRIBUTING.md) and come to [SIG-Storage meetings](https://github.com/kubernetes/community/tree/master/sig-storage) to find a project that you are interested in helping with. Help make code contributions and learn how storage works in Kubernetes. After you are getting familiar with the code, help with code reviews.
