 **Android permissions note**
 
 An app that uses the library have to add the following permissions to `AndroidManifest.xml`:
  * `<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>`
  * `<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>`
 
 (added automatically if building with Gradle or should be added manually otherwise).
 
+### Building with prebuilt shared V8
+
+This can be desired to use product's V8 (let's say Chromium) instead of libadblockplus built-in V8.
+Put prebuilt shared V8 library file in ARCH directories and set `SHARED_V8_LIB_FILENAME`
+environment variable before building. Libadblockplus is required to be linked with that library file.
+
+For example (build with Gradle):
+
+    SHARED_V8_LIB_FILENAME=libswev8.so ./gradlew clean assemble
+    
+Note `[Configuration] Linking dynamically with shared v8 library ./libadblockplus-binaries/android_armeabi-v7a/libv8.cr.so`
+output while building native library.
