Consider moving material from the README to [`.github/CONTRIBUTING`](https://help.github.com/articles/setting-guidelines-for-repository-contributors/). Also consider creating [`.github/PULL_REQUEST_TEMPLATE`](https://blog.github.com/2016-02-17-issue-and-pull-request-templates/) that says to run `yarn lint` and (once it exists) `yarn test`.
