 ```
+Here's how you use `appsFlyer.logAdRevenue` within a Cordova app:
+
+1. Prepare the `adRevenueData` object as shown, including any additional parameters you wish to track along with the ad revenue event.
+2. Call the `appsFlyer.logAdRevenue` method with the `adRevenueData` object.
+
+By passing all the required fields in `AFAdRevenueData`, you help ensure accurate tracking within the AppsFlyer platform. This enables you to analyze your ad revenue alongside other user acquisition data to optimize your app's overall monetization strategy.
 
+**Note:** 
+The `additionalParameters` object is optional. You can add any additional data you want to log with the ad revenue event in this object. This can be useful for detailed analytics or specific event tracking later on. Make sure that the custom parameters follow the data types and structures specified by AppsFlyer in their documentation.
