+## Getting Started
+
+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, view our 
+[online documentation](https://flutter.dev/docs), which offers tutorials, 
+samples, guidance on mobile development, and a full API reference.
