 ### Small and large icons on Android
 By default all notifications will display the app icon. But an specific icon can be defined through the `icon` and `smallIcon` properties.
 
+#### Resource icons
+The following example shows how to display the `<package.name>.R.drawable.ic_launcher`icon as the notifications icon.
+
 ```javascript
-/**
- * Displays the <package.name>.R.drawable.ic_launcher icon
- */
 window.plugin.notification.local.add({ icon: 'ic_launcher' });
+```
 
-/**
- * Displays the android.R.drawable.ic_dialog_email icon
- */
+See below how to use the `android.R.drawable.ic_dialog_email` icon as the notifications small icon.
+
+```javascript
 window.plugin.notification.local.add({ smallIcon: 'ic_dialog_email' });
 ```
 
+#### Local icons
+The `icon` property also accepts local file URIs. The URI points to a relative path within the www folder.
+
+```javascript
+window.plugin.notification.local.add({ icon: 'file://img/logo.png' }); //=> /assets/www/img/logo.png
+```
+
+#### Remote icons
+The `icon` property also accepts remote URLs. If the device cannot download the image, it will fallback to the app icon.
+
+```javascript
+window.plugin.notification.local.add({ icon: 'https://cordova.apache.org/images/cordova_bot.png' });
+```
+
 ### Notification sound on Android
 The sound must be a absolute or relative Uri pointing to the sound file. The default sound is `RingtoneManager.TYPE_NOTIFICATION`.
