Then add this block to the `package.json` file of your project:
```js
{
// ...
"eslintConfig": {
"extends": "react-app"
}
}
```
Finally, you will need to install some packages *globally*:
```sh
npm install -g eslint-config-react-app@0.2.1 eslint@3.5.0 babel-eslint@6.1.2 eslint-plugin-react@6.3.0 eslint-plugin-import@1.12.0 eslint-plugin-jsx-a11y@2.2.2 eslint-plugin-flowtype@2.18.1
```
We recognize that this is suboptimal, but it is currently required due to the way we hide the ESLint dependency. The ESLint team is already [working on a solution to this](https://github.com/eslint/eslint/issues/3458) so this may become unnecessary in a couple of months.
## Installing a Dependency
The generated project includes React and ReactDOM as dependencies. It also includes a set of scripts used by Create React App as a development dependency. You may install other dependencies (for example, React Router) with `npm`:
```
npm install --save
