If you want to enable even more accessibility rules, you can create an `.eslintrc` file in the root of your project with this content:
59+
60+
```json
61+
{
62+
"extends": ["react-app", "plugin:jsx-a11y/recommended"],
63+
"plugins": ["jsx-a11y"]
64+
}
65+
```
66+
67+
However, if you are using [Create React App](https://github.com/facebookincubator/create-react-app) and have not ejected, any additional rules will only be displayed in the [IDE integrations](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#displaying-lint-output-in-the-editor), but not in the browser or the terminal.
