-## Getting Started
+A comic reader that support reading local and network comics.
 
-This project is a starting point for a Flutter application.
+## Features
 
-A few resources to get you started if this is your first Flutter project:
+- Read local comics
+- Use javascript to create comic sources
+- Read comics from network sources
+- Manage favorite comics
+- Download comics
+- View comments, tags, and other information of comics if the source supports
+- Login to comment, rate, and other operations if the source supports
 
-- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
-- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+## Build from source
 
-For help getting started with Flutter development, view the
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
+1. Clone the repository
+2. Install flutter, see [flutter.dev](https://flutter.dev/docs/get-started/install)
+3. Install rust, see [rustup.rs](https://rustup.rs/)
+4. Build for your platform: e.g. `flutter build apk`
