## Installing React
### Creating a new React project
You could just embed the React library in your webpage like so<sup>2</sup>:
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.0.0/cjs/react.production.min.js"></script>
```

Smart programmers want to take the more practical and productive way: [Create React App](https://github.com/facebookincubator/create-react-app)
```bash
npm install -g create-react-app
create-react-app my-app

cd my-app
npm start
```

This will set up your development environment so that you can use the latest JavaScript features, provide a nice developer experience, and optimize your app for production.

`npm start` will start up a development server which allows live reloading<sup>3</sup>.

After you finish your project and are ready to deploy your App to production, you can just use
`npm run build`
to create an optimized build of your app in the `build`folder.
