 ## Platform specific setup
 ### Android
-This packages uses the **bundled version** of MLKit Barcode-scanning for Android. This version is more accurate and immediately available to devices. However, this version will increase the size of the app with approximately 3 to 10 MB. The alternative for this is to use the **unbundled version** of MLKit Barcode-scanning for Android. This version is older than the bundled version however this only increases the size by around 600KB.
-To use this version you must alter the mobile_scanner gradle file to replace `com.google.mlkit:barcode-scanning:17.0.2` with `com.google.android.gms:play-services-mlkit-barcode-scanning:18.0.0`. Keep in mind that if you alter the gradle files directly in your project it can be overriden when you update your pubspec.yaml. I am still searching for a way to properly replace the module in gradle but have yet to find one.
+This package uses by default the **bundled version** of MLKit Barcode-scanning for Android. This version is immediately available to the device. But it will increase the size of the app by approximately 3 to 10 MB.

+The alternative is to use the **unbundled version** of MLKit Barcode-scanning for Android. This version is downloaded on first use via Google Play Services. It increases the app size by around 600KB.
 
 [You can read more about the difference between the two versions here.](https://developers.google.com/ml-kit/vision/barcode-scanning/android)
 
+To use the **unbundled version** of the MLKit Barcode-scanning, add the following line to your `/android/gradle.properties` file:
+```
+dev.steenbakker.mobile_scanner.useUnbundled=true
+```
