+## Dynamic notifications customisation
+You have the possibility to let your code modify every notification before they are display to the use.
+In order to achieve this, you had to :
+# Add the NotificationService.NotificationModifier interface to the class which will be responsible of the notifications customisation.
+# Register the previous class with 
+```java
+NotificationService.registerNotificationModifier(this);
+```
+# Implements the two methods :
+```java
+    public String modifyNotificationTitle(Bundle extras) {
+        
+    }
+
+    public String modifyNotificationMessage(Bundle extras) {
+        
+    }
+```

 ## Android 6
 
 With Android 6.0 (API level 23) a new permission system was introduced by Google. On Android 6 devices, users can manually manage permissions on a per-application basis. If an app targets Android 6 (using targetSdkVersion 23 and compileSdkVersion 23), an app also needs to deal with runtime permissions. This means that permissions such as location access (which is now a so-called 'dangerous' permission) needs to be explicitly requested with a permission request pop-up. Until SDK version 1.4.2, the B4S SDK does not handle this automatically and therefor the integrator needs to [handle permission request dialogs manually](https://developer.android.com/training/permissions/requesting.html).
