+### iOS

 Add `RNI18n.xcodeproj` to **Libraries** and add `libRNI18n.a` to **Link Binary With Libraries** under **Build Phases**. [More info and screenshots about how to do this is available in the React Native documentation](http://facebook.github.io/react-native/docs/linking-libraries.html).
 
+### Android
+
+Add `react-native-i18n` to your `./android/settings.gradle` file as follows:
+
+```
+include ':app', ':react-native-i18n'
+project(':react-native-i18n').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-i18n/android')
+```

+Include it as dependency in `./android/app/build.gradle` file:
+
+```
+dependencies {
+    ...
+    compile project(':react-native-i18n')
+}
+```
+
+Finally, you need to add the package within the `ReactInstanceManager` of your MainActivity (`./android/app/src/main/java/your/bundle/MainActivity.java`):
+
+```java
+
+import com.i18n.reactnativei18n.ReactNativeI18n;  // <---- import this one

+protected void onCreate(Bundle savedInstanceState) {

+	.addPackage(new ReactNativeI18n())  // <---- add this line
+	.build();
+
+	...
+}
+
+...
+
+```
+
+
+After that, you will need to recompile your project with `react-native run-android`.

 ### Device's locale

 You can get the device's locale with the `RNI18n` native module:
