 # wireguard_dart
 
-A new Flutter plugin project.
+A flutter plugin to setup and control VPN connection via [Wireguard](https://www.wireguard.com/) tunnel.
 
-## Getting Started
+|             | Android | iOS   | Linux | macOS | Windows     |
+|-------------|---------|-------|-------|-------|-------------|
+| **Support** | TBD     | 15.0+ | TBD   | 12+   | TBD         |
 
-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.
+## Usage
 
-For help getting started with Flutter development, view the
-[online documentation](https://flutter.dev/docs), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
+To use this plugin, add `wireguard_dart` as a [dependency in your pubspec.yaml file](https://flutter.dev/platform-plugins/).
