+## WebView
+
+You can find 'AdblockWebView' class in 'libadblockplus-android-webview' directory.
+
+`AdblockWebView` class provides built-in ad blocking
+(both resource loading filtering and element hiding) and inherits from Android
+['WebView'](https://developer.android.com/reference/android/webkit/WebView.html).
+
+### Usage
+
+In layout XML:
+
+    <org.adblockplus.android.AdblockWebView
+        android:id="@+id/main_webview"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent"/>
+
+In java source code:
+
+    AdblockWebView webView = (AdblockWebView) findViewById(R.id.main_webview);
+
+Use `setDebugMode(boolean debugMode)` to turn debug log output (Android log and JS console) on/off.
+
+Use `setAllowDrawDelay(int allowDrawDelay)` to set custom delay to start render webpage after 'DOMContentLoaded' event is fired.
+
+Use `setFilterEngine(FilterEngine newFilterEngine)` to use external filter engine
+If filter engine is not set, it's created by AdblockWebView instance automatically.
+
+Use `setAcceptableAdsEnabled(boolean enabled)` to enable/disable Acceptable Ads.
+
+Use `dispose()` to release resources (**required**).
+
+### Building
+
+Building with Ant
+-----------------
+
+In the 'libadblockplus-android-webview' directory create the file _local.properties_ and set
+_sdk.dir_ to where you installed it, e.g.:
+
+    sdk.dir = /some/where/sdk
+
+Then run:
+
+    ant debug
+
+
+Building with Gradle
+--------------------
+
+In the project root directory run:
+
+    ./gradlew assemble
+
+This will generate *.aar in 'libadblockplus-android-webview/build/outputs/aar' directory.
+
+## WebView Application
+
+You can find demo application for 'AdblockWebView' class in
+'libadblockplus-android-webviewapp' directory.
+
+### Building
+
+Make sure _Library_ requirements are present.
+
+Building with Ant
+-----------------
+
+In the 'libadblockplus-android-webviewapp' directory create the file _local.properties_ and set
+_sdk.dir_ to where you installed it, e.g.:
+
+    sdk.dir = /some/where/sdk
+
+Then run:
+
+    ant debug
+
+This will generate *.apk in 'libadblockplus-android-webviewapp/bin/' directory.
+
+Building with Gradle
+--------------------
+
+In the project root directory run:
+
+    ./gradlew assemble
+
+This will generate *.apk in 'libadblockplus-android-webviewapp/build/outputs/apk/' directory.
