 # react-native-dialogs
 React Native wrappers for https://github.com/afollestad/material-dialogs
+
+Installation
+------------
+
+Install the npm package 'react-native-dialogs'. Inside your React Native project, run :
+```bash
+npm install --save react-native-dialogs
+```
+Changes to your `package.json` should look like [this](https://github.com/aakashns/react-native-dialogs-example/commit/e6b83bf3d2238cf7e4ec3688519f38b2544ccad5).
+
+In `android/settings.gradle`, remove the line `include ':app'` and add the following lines :
+```
+include ':app', ':react-native-dialogs'
+project(':react-native-dialogs').projectDir = file('../node_modules/react-native-dialogs/android')
+```
+The changes should look like [this](https://github.com/aakashns/react-native-dialogs-example/commit/32b4159725601e0ea17e140f0a9b62161d567804)
+**NOTE** : If you have included other libraries in your project, the `include` line will contain the other dependencies too, apart from `':app'` and `':react-native-dialogs'`
+
+In `android/app/build.gradle`, add a dependency to `':react-native-dialogs'` and URL of the Jitpack maven repository (to download the library https://github.com/afollestad/material-dialogs) :
+```
+repositories {
+    maven { url "https://jitpack.io" }
+}
+
+dependencies {
+    // after other dependencies
+    compile project(':react-native-dialogs')
+}
+```
+The changes should look like [this](https://github.com/aakashns/react-native-dialogs-example/commit/b58086d8fb9ece99f0e678dd8bf0e689a856bd43)
+
+Next, you need to change the `MainActivity` of your app to extends `FragmentActivity` instead of `Activity` (otherwise dialogs will not be rendered), and register `ReactNativeDialogsPackage` : 
+```java
+import android.support.v4.app.FragmentActivity;
+import com.aakashns.reactnativedialogs.ReactNativeDialogsPackage;
+
+public class MainActivity extends FragmentActivity implements DefaultHardwareBackBtnHandler {
+    //...
+  
+          mReactInstanceManager = ReactInstanceManager.builder()
+                //...
+                .addPackage(new MainReactPackage())
+                .addPackage(new ReactNativeDialogsPackage(this)) // <- ADD THIS LINE!
+                //...
+                .build();
+
+```
+See [this changelog](https://github.com/aakashns/react-native-dialogs-example/commit/52cac27756963bcd2f4fdcd039e1a78028bb0abd) for reference
+
+Now you're finally ready to start using module in your React Native application. See [this changelog](https://github.com/aakashns/react-native-dialogs-example/commit/2d8e02c22275479d2fbbb89f99dcb846834bec9d) for an example that uses `DialogAndroid`.
