 ### Accessing the underlying Firebase SDK
 
-In some cases you might want to access the underlying official Firebase SDK in platform specific code, for example when the common API is missing the functionality you need. For this purpose each class in the SDK has `android`, `ios` and `js` properties which holds the  equivalent object of the underlying official Firebase SDK. 
+In some cases you might want to access the underlying official Firebase SDK in platform specific code, for example when the common API is missing the functionality you need. For this purpose each class in the SDK has `android`, `ios` and `js` properties which holds the  equivalent object of the underlying official Firebase SDK. For *JVM*, as the `firebase-java-sdk` is a direct port of the Firebase Android SDK, is it also accessed via the `android` property.
 
 These properties are only accessible from the equivalent target's source set. For example to disable persistence in Cloud Firestore on Android you can write the following in your Android specific code (e.g. `androidMain` or `androidTest`):
