+# Recommended configuration
+
+This plugin export a `recommended` configuration that enforce React good practices.
+
+To enable this configuration use the `extends` property in your `.eslintrc` config file:

+    "react"
+  ],
+  "extends": "plugin:react/recommended"
+}
+```
+
+See [ESLint documentation](http://eslint.org/docs/user-guide/configuring#extending-configuration-files) for more information about extending configuration files.
+
+The rules enabled in this configuration are:
+
+* [display-name](docs/rules/display-name.md)
+* [jsx-no-duplicate-props](docs/rules/jsx-no-duplicate-props.md)
+* [jsx-no-undef](docs/rules/jsx-no-undef.md)
+* [jsx-uses-react](docs/rules/jsx-uses-react.md)
+* [jsx-uses-vars](docs/rules/jsx-uses-vars.md)
+* [no-danger](docs/rules/no-danger.md)
+* [no-deprecated](docs/rules/no-deprecated.md)
+* [no-did-mount-set-state](docs/rules/no-did-mount-set-state.md) with `allow-in-func` option
+* [no-did-update-set-state](docs/rules/no-did-update-set-state.md) with `allow-in-func` option
+* [no-direct-mutation-state](docs/rules/no-direct-mutation-state.md)

+* [prop-types](docs/rules/prop-types.md)
