+== Introduction
+
+Couchbase Lite on Android 3.x supports the development of applications in Java or {kotlin--xref}.
+You can install Kotlin and-or Java from (separate) downloads or by using the Maven repository.
+
+When using Maven, selecting Kotlin will also pull-in the pure Java version.
+Users requiring only Java can choose to just pull the Java version.
+
+== Install
+
 Create or open an existing Android Studio project and install Couchbase Lite using the following method.
 
-Make the following additions to the module-level `build.gradle` file (typically in the *app* folder).
-*Note:* In the gradle examples replace the `${version}` token with the required Couchbase Lite version number.
+Add the following entries to the module-level `build.gradle` file (typically in the *app* folder).
