diff --git a/create-react-app-for-testing b/create-react-app-for-testing
 create-react-app comes with Jest which is awesome, but sometimes you need a real DOM/browser to test with. Here's a quick way to get up and running testing your app.

 1. Create a *separate* app for testing, using create-react-app:
 ```
 create-react-app tests
 cd tests
 ```

 2. Modify the index.html to include the Jasmine spec runner (see index.html below)
 3. Modify the index.js to just run your tests rather than bootstrap a React app. (see index.js below)

 Happy testing!
