 ## Writing and Running Tests
 
-This project is set up to use [jest](https://facebook.github.io/jest/) for tests. You can configure whatever testing strategy you like, but jest works out of the box. Create test files in directories called `__tests__` or with the `.test` extension to have the files loaded by jest. See the [the template project](https://github.com/react-community/create-react-native-app/blob/master/react-native-scripts/template/App.test.js) for an example test. The [jest documentation](https://facebook.github.io/jest/docs/getting-started.html) is also a wonderful resource, as is the [React Native testing tutorial](https://facebook.github.io/jest/docs/tutorial-react-native.html).

-## Adding Flow
-
-Flow is a static type checker that helps you write code with fewer bugs. Check out this [introduction to using static types in JavaScript](https://medium.com/@preethikasireddy/why-use-static-types-in-javascript-part-1-8382da1e0adb) if you are new to this concept.
-
-React Native works with [Flow](http://flowtype.org/) out of the box, as long as your Flow version matches the one used in the version of React Native.
-
-To add a local dependency to the correct Flow version to a Create React Native App project, follow these steps:
-
-1. Find the Flow `[version]` at the bottom of the included [.flowconfig](.flowconfig)
-2. Run `npm install --save-dev [email protected]` (or `yarn add --dev [email protected]`), where `x.y.z` is the .flowconfig version number.
-3. Add `"flow": "flow"` to the `scripts` section of your `package.json`.
-4. Add `// @flow` to any files you want to type check (for example, to `App.js`).
-
-Now you can run `npm run flow` (or `yarn flow`) to check the files for type errors.
-You can optionally use a [plugin for your IDE or editor](https://flow.org/en/docs/editors/) for a better integrated experience.
-
-To learn more about Flow, check out [its documentation](https://flow.org/).

 ## Sharing and Deployment
 
 Create React Native App does a lot of work to make app setup and development simple and straightforward, but it's very difficult to do the same for deploying to Apple's App Store or Google's Play Store without relying on a hosted service.
