+# eslint-config-react-app
+
+This package includes the shareable ESLint configuration used by [Create React App](https://github.com/facebook/create-react-app).<br>
+Please refer to its documentation:
+
+- [Getting Started](https://facebook.github.io/create-react-app/docs/getting-started) – How to create a new app.
+- [User Guide](https://facebook.github.io/create-react-app/) – How to develop apps bootstrapped with Create React App.
+
+## Usage in Create React App Projects
+
+The easiest way to use this configuration is with [Create React App](https://github.com/facebook/create-react-app), which includes it by default.
+
+**You don’t need to install it separately in Create React App projects.**
+
+## Usage Outside of Create React App
+
+If you want to use this ESLint configuration in a project not built with Create React App, you can install it with the following steps.
+
+First, install this package, ESLint and the necessary plugins.
+
+```sh
+npm install --save-dev eslint-config-react-app babel-eslint@9.x eslint@5.x eslint-plugin-flowtype@2.x eslint-plugin-import@2.x eslint-plugin-jsx-a11y@6.x eslint-plugin-react@7.x
+```
+
+Then create a file named `.eslintrc.json` with following contents in the root folder of your project:
+
+```json
+{
+  "extends": "react-app"
+}
+```
+
+That's it! You can override the settings from `eslint-config-react-app` by editing the `.eslintrc.json` file. Learn more about [configuring ESLint](http://eslint.org/docs/user-guide/configuring) on the ESLint website.
+
+## Accessibility Checks
+
+The following rules from the [eslint-plugin-jsx-a11y](https://github.com/evcohen/eslint-plugin-jsx-a11y) plugin are activated:
+
+- [accessible-emoji](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/accessible-emoji.md)
+- [alt-text](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/alt-text.md)
+- [anchor-has-content](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/anchor-has-content.md)
+- [aria-activedescendant-has-tabindex](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/aria-activedescendant-has-tabindex.md)
+- [aria-props](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/aria-props.md)
+- [aria-proptypes](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/aria-proptypes.md)
+- [aria-role](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/aria-role.md)
+- [aria-unsupported-elements](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/aria-unsupported-elements.md)
+- [heading-has-content](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/heading-has-content.md)
+- [href-no-hash](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/v5.1.1/docs/rules/href-no-hash.md)
+- [iframe-has-title](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/iframe-has-title.md)
+- [img-redundant-alt](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/img-redundant-alt.md)
+- [no-access-key](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/no-access-key.md)
+- [no-distracting-elements](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/no-distracting-elements.md)
+- [no-redundant-roles](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/no-redundant-roles.md)
+- [role-has-required-aria-props](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/role-has-required-aria-props.md)
+- [role-supports-aria-props](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/role-supports-aria-props.md)
+- [scope](https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/scope.md)
+
+If you want to enable even more accessibility rules, you can create an `.eslintrc.json` file in the root of your project with this content:
+
+```json
+{
+  "extends": ["react-app", "plugin:jsx-a11y/recommended"],
+  "plugins": ["jsx-a11y"]
+}
+```
+
+However, if you are using [Create React App](https://github.com/facebook/create-react-app) and have not ejected, any additional rules will only be displayed in the [IDE integrations](https://facebook.github.io/create-react-app/docs/setting-up-your-editor#displaying-lint-output-in-the-editor), but not in the browser or the terminal.
