+# Play Billing
+
+The Play Billing module provides capabilities for your TWA app to connect with [Google Play Billing library](https://developer.android.com/google/play/billing), for example you can:
+
+* Query purchase history
+* Initialize a payment
+* Query SKU details
+
+The module uses [Version 5](https://developer.android.com/google/play/billing/release-notes#5-2-1)  of Play Billing library.
+
+
+## How to use it? (Website)
+To use this API from your website you can do it as follows:
+```js
+const PAYMENT_METHOD = 'https://play.google.com/billing'; 
+const SKUS = [  
+     'android.test.purchased',  
+     'android.test.canceled', 
+] 
+
+const service = await window.getDigitalGoodsService(PAYMENT_METHOD); 
+const details = await service.getDetails(SKUS);
+console.log(details);
+```
+
+## How to use it? (Android Project)
+To use it from your Android project you will need to do two steps:
+Add this to your `AndroidManifest.xml`
+
+```xml
+      <activity
+            android:name="com.google.androidbrowserhelper.playbilling.provider.PaymentActivity"
+            android:theme="@android:style/Theme.Translucent.NoTitleBar"
+            android:configChanges="keyboardHidden|keyboard|orientation|screenLayout|screenSize"
+            android:exported="true">
+
+            <intent-filter>
+                <action android:name="org.chromium.intent.action.PAY" />
+            </intent-filter>
+
+            <meta-data
+                android:name="org.chromium.default_payment_method_name"
+                android:value="https://play.google.com/billing" />
+      </activity>
+
+      <service
+            android:name="com.google.androidbrowserhelper.playbilling.provider.PaymentService"
+            android:exported="true" >
+            <intent-filter>
+                <action android:name="org.chromium.intent.action.IS_READY_TO_PAY" />
+            </intent-filter>
+      </service>
+```
+
+Create a new Service that extends `DelegationService` with this line in `onCreate()` method:
+```java
+registerExtraCommandHandler(new DigitalGoodsRequestHandler(getApplicationContext()));
+```
+Then add it to your AndroidManifest and make it exported (`android:exported="true"`).
+
+
