 ### BREAKING CHANGES
 
 - Plugin conversion to a [Federated Plugin](https://docs.flutter.dev/packages-and-plugins/developing-packages#federated-plugins) to better support multiple environments and implementations.
+- Dart SDK min version `>= 2.17.0`
 - Android package name has been changed to `com.pichillilorenzo.flutter_inappwebview_android`. References to old package name `com.pichillilorenzo.flutter_inappwebview` should be updated, for example inside `AndroidManifest.xml` file: `<provider android:name="com.pichillilorenzo.flutter_inappwebview_android.InAppWebViewFileProvider" android:authorities="${applicationId}.flutter_inappwebview_android.fileprovider" ...`
 - Web Platform: `web_support.js` file path has been changed to `packages/flutter_inappwebview_web/assets/web/web_support.js`

-## Getting Started
+## Usage
 
-This project is a starting point for a Flutter
-[plug-in package](https://flutter.dev/developing-packages/),
-a specialized package that includes platform-specific implementation code for
-Android and/or iOS.

-For help getting started with Flutter development, view the

+This package is [endorsed][https://flutter.dev/docs/development/packages-and-plugins/developing-packages#endorsed-federated-plugin],
+which means you can simply use `flutter_inappwebview`
+normally. This package will be automatically included in your app when you do,
+so you do not need to add it to your `pubspec.yaml`.
 
+However, if you `import` this package to use any of its APIs directly, you
+should add it to your `pubspec.yaml` as usual.

+# flutter\_inappwebview\_platform\_interface
 
-For information about how to write a good package README, see the guide for
-[writing package pages](https://dart.dev/guides/libraries/writing-package-pages).
+A common platform interface for the [`flutter_inappwebview`][https://pub.dev/packages/flutter_inappwebview] plugin.
 
-For general information about developing packages, see the Dart guide for
-[creating packages](https://dart.dev/guides/libraries/create-library-packages)
-and the Flutter guide for
-[developing packages and plugins](https://flutter.dev/developing-packages).
--->
+This interface allows platform-specific implementations of the `flutter_inappwebview`
+plugin, as well as the plugin itself, to ensure they are supporting the
+same interface.
 
-TODO: Put a short description of the package here that helps potential users
-know whether this package might be useful for them.
+# Usage
 
-## Features
+To implement a new platform-specific implementation of `flutter_inappwebview`, extend
+[`InAppWebViewPlatform`](lib/src/inappwebview_platform.dart) with an implementation that performs the
+platform-specific behavior, and when you register your plugin, set the default
+`InAppWebViewPlatform` by calling
+`InAppWebViewPlatform.instance = MyPlatformWebview()`.
 
-TODO: List what your package can do. Maybe include images, gifs, or videos.
+# Note on breaking changes
 
-## Getting started
+Strongly prefer non-breaking changes (such as adding a method to the interface)
+over breaking changes for this package.
 
-TODO: List prerequisites and provide or point to information on how to
-start using the package.
-
-## Usage
-
-TODO: Include short and useful examples for package users. Add longer examples
-to `/example` folder.
-
-```dart
-const like = 'sample';
-```
-
-## Additional information
-
-TODO: Tell users more about the package: where to find more information, how to
-contribute to the package, how to file issues, what response they can expect
-from the package authors, and more.
+See https://flutter.dev/go/platform-interface-breaking-changes for a discussion
+on why a less-clean interface is preferable to a breaking change.
