+You can run `yarn test` to execute the test suite and linters. To help you develop the component we’ve set up some tests that cover the basic functionality (can be found in `/tests`). Even though we’re big fans of testing, this only covers a small piece of the component. We highly recommend you add tests when you’re adding new functionality.
