+# `@react-navigation/drawer`
+
+Bottom tab navigator for React Navigation following iOS design guidelines.
+
+## Installation
+
+Open a Terminal in your project's folder and run,
+
+```sh
+yarn add @react-navigation/drawer
+```
+
+Now we need to install [`react-native-gesture-handler`](https://github.com/kmagiera/react-native-gesture-handler) and [`react-native-reanimated`](https://github.com/kmagiera/react-native-reanimated).
+
+If you are using Expo, to ensure that you get the compatible versions of the libraries, run:
+
+```sh
+expo install react-native-gesture-handler react-native-reanimated
+```
+
+If you are not using Expo, run the following:
+
+```sh
+yarn add react-native-reanimated react-native-gesture-handler
+```
+
+If you are using Expo, you are done. Otherwise, continue to the next steps.
+
+Next, we need to link these libraries. The steps depends on your React Native version:
+
+- **React Native 0.60 and higher**
+
+  On newer versions of React Native, [linking is automatic](https://github.com/react-native-community/cli/blob/master/docs/autolinking.md).
+
+  To complete the linking on iOS, make sure you have [Cocoapods](https://cocoapods.org/) installed. Then run:
+
+  ```sh
+  cd ios
+  pod install
+  cd ..
+  ```
+
+- **React Native 0.59**
+
+  If you're on an older React Native version, you need to manually link the dependencies. To do that, run:
+
+  ```sh
+  react-native link react-native-reanimated
+  react-native link react-native-gesture-handler
+  ```
+
+**IMPORTANT:** There are additional steps required for `react-native-gesture-handler` on Android after linking (for all React Native versions). Check the [this guide](https://kmagiera.github.io/react-native-gesture-handler/docs/getting-started.html) to complete the installation.
+
+## Usage
+
+```js
+import { createDrawerNavigator } from '@react-navigation/drawer';
+
+const Drawer = createDrawerNavigator();
+
+export default function App() {
+  return (
+    <Drawer.Navigator>
+      <Drawer.Screen name="home" component={Home} options={{ title: 'Home' }} />
+      <Drawer.Screen name="feed" component={Feed} options={{ title: 'Feed' }} />
+      <Drawer.Screen
+        name="profile"
+        component={Profile}
+        options={{ title: 'Profile' }}
+      />
+    </Drawer.Navigator>
+  );
+}
+```
