-#### Android
+### Android
 
 1. Open up `android/app/src/main/java/[...]/MainApplication.java`
   - Add `import com.reactlibrary.RNSyanImagePickerPackage;` to the imports at the top of the file
   - Add `new RNSyanImagePickerPackage()` to the list returned by the `getPackages()` method
 2. Append the following lines to `android/settings.gradle`:
-  	```
+  	```gradle
   	include ':react-native-syan-image-picker'
   	project(':react-native-syan-image-picker').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-syan-image-picker/android')
   	```
 3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
