-# Welcome to your Expo app 👋
+# RSSuper - Native Multi-Platform RSS Reader

-This is an [Expo](https://expo.dev) project created with [`create-expo-app`](https://www.npmjs.com/package/create-expo-app).
+A native RSS reader built for iOS, macOS, Android, Linux, and Windows.

-## Get started
+## Architecture

-1. Install dependencies
+RSSuper uses a native-first approach, building truly native applications for each platform:

-   ```bash
-   npm install
-   ```
+| Platform | Language | UI Framework | Status |
+|----------|----------|--------------|--------|
+| iOS | Swift | SwiftUI | ✅ Active |
+| macOS | Swift | SwiftUI | ✅ Active |
+| Android | Kotlin | Jetpack Compose | 🚧 Setup |
+| Linux | C/Vala | GTK4 + Libadwaita | 🚧 Setup |
+| Windows | C# | WinUI 3 | 🔜 Planned |

-2. Start the app
+## Quick Start

-   ```bash
-   npx expo start
-   ```
-
-In the output, you'll find options to open the app in a
-
- [development build](https://docs.expo.dev/develop/development-builds/introduction/)
- [Android emulator](https://docs.expo.dev/workflow/android-studio-emulator/)
- [iOS simulator](https://docs.expo.dev/workflow/ios-simulator/)
- [Expo Go](https://expo.dev/go), a limited sandbox for trying out app development with Expo
-
-You can start developing by editing the files inside the **app** directory. This project uses [file-based routing](https://docs.expo.dev/router/introduction).
-
-## Get a fresh project
-
-When you're ready, run:
+### Build All Platforms

 ```bash
-npm run reset-project
+./scripts/build.sh
 ```

-This command will move the starter code to the **app-example** directory and create a blank **app** directory where you can start developing.
+### Build Specific Platform

-### Other setup steps
+```bash
+# iOS/macOS
+./scripts/build.sh -p ios

- To set up ESLint for linting, run `npx expo lint`, or follow our guide on ["Using ESLint and Prettier"](https://docs.expo.dev/guides/using-eslint/)
- If you'd like to set up unit testing, follow our guide on ["Unit Testing with Jest"](https://docs.expo.dev/develop/unit-testing/)
- Learn more about the TypeScript setup in this template in our guide on ["Using TypeScript"](https://docs.expo.dev/guides/typescript/)
+# Android
+./scripts/build.sh -p android

-## Learn more
+# Linux
+./scripts/build.sh -p linux
+```

-To learn more about developing your project with Expo, look at the following resources:

+# RSSuper - Multi-Platform Native Build System
+
+This directory contains the build infrastructure for building RSSuper natively across multiple platforms.
+
+## Architecture

+├── linux/        - Linux app (C/Vala + GTK4)
+│   └── (auto-generated on first build)
+└── windows/      - Windows app (TODO)
+```
+
+## Quick Start
+
+### Build All Platforms
+
+```bash
+# From project root
+./scripts/build.sh
+```
+
+### Build Specific Platform
+
+```bash
+# iOS/macOS only
+./scripts/build.sh -p ios
+
+# Android only
+./scripts/build.sh -p android
+
+# Linux only
+./scripts/build.sh -p linux
+
+# Multiple platforms
+./scripts/build.sh -p ios,android
+```
+
+### Build Types
+
+```bash
+# Debug build (default)
+./scripts/build.sh -t debug
+
+# Release build
+./scripts/build.sh -t release
+```
+
+### Run Tests
+
+```bash
+# Build and test all platforms
+./scripts/build.sh --test
+
+# Test specific platform
+./scripts/build.sh -p ios --test
+```
+
+### Clean Build
+
+```bash
+# Clean all platforms
+./scripts/build.sh -a clean
+
+# Clean specific platform
+./scripts/build-ios.sh clean
+./scripts/build-android.sh clean
+./scripts/build-linux.sh clean
+```
+
+## Individual Platform Scripts
+
+### iOS/macOS
+
+```bash
+# Build
+./scripts/build-ios.sh [Debug|Release] [iOS|macOS] [destination] [action]
+
+# Examples
+./scripts/build-ios.sh                          # Debug iOS
+./scripts/build-ios.sh Release                  # Release iOS
+./scripts/build-ios.sh Debug iOS "platform=iOS Simulator,name=iPhone 15"
+./scripts/build-ios.sh clean
+./scripts/build-ios.sh Debug iOS "generic/platform=iOS" test
+```
+
+### Android
+
+```bash
+# Build
+./scripts/build-android.sh [debug|release] [assemble|build|test|clean]
+
+# Examples
+./scripts/build-android.sh                    # Assemble debug
+./scripts/build-android.sh release            # Assemble release
+./scripts/build-android.sh debug test         # Run tests
+./scripts/build-android.sh clean              # Clean
+```
+
+### Linux
+
+```bash
+# Build
+./scripts/build-linux.sh [debug|release] [build|install|test|clean|setup]
+
+# Examples
+./scripts/build-linux.sh                     # Build debug
+./scripts/build-linux.sh release             # Build release
+./scripts/build-linux.sh debug setup         # Setup build environment
+./scripts/build-linux.sh debug install-deps  # Install dependencies
+./scripts/build-linux.sh debug run           # Build and run
+./scripts/build-linux.sh clean               # Clean
+```
+

+
+## Project Structure Template
+
+When you add shared code, use this structure:
+
+```
+RSSuper/
+├── native-route/
+│   ├── common/           # Shared code (if using a shared language)
+│   ├── ios/
+│   │   └── RSSuper/
+│   ├── android/
+│   ├── linux/
+│   └── windows/
+├── scripts/
+│   ├── build.sh          # Main build orchestrator
+│   ├── build-ios.sh      # iOS/macOS builder
+│   ├── build-android.sh  # Android builder
+│   ├── build-linux.sh    # Linux builder
+│   └── common.sh         # Shared utilities
+└── .github/
+    └── workflows/
+        └── ci.yml        # CI configuration
+```
+
+## Migration Notes
+
+Build scripts adapted from Nessa project:
+- Xcode version selection logic
+- Build report generation
+- Error extraction and display
+- CI workflow structure
+
+## Troubleshooting
+
+### iOS Build Fails
+
+```bash
+# Check Xcode installation
+xcodebuild -version
+
+# Select Xcode manually
+sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
+
+# Clean DerivedData
+rm -rf ~/Library/Developer/Xcode/DerivedData/RSSuper-*
+```
+
+### Android Build Fails
+
+```bash
+# Check Java installation
+java -version
+
+# Check Android SDK
+echo $ANDROID_HOME
+
+# Run with more verbose output
+./scripts/build-android.sh debug assemble --info
+```
+
+### Linux Build Fails
+
+```bash
+# Install dependencies (Ubuntu/Debian)
+sudo apt install meson ninja-build pkg-config libgtk-4-dev libadwaita-1-dev
+
+# Check meson installation
+meson --version
+
+# Setup build manually
+cd native-route/linux
+meson setup build --buildtype=debug
+```
+
+## Future Enhancements
+
+- [ ] Windows support (Win32 + DirectUI or WebView2)
+- [ ] Shared business logic layer
+- [ ] Cross-platform test suite
+- [ ] Automated code signing
+- [ ] App store deployment scripts
+- [ ] Performance benchmarking

+- 02 → 03, 04, 05 (data models depend on shared design)
+- 03 → 06 (iOS database depends on iOS models)
+- 04 → 07 (Android database depends on Android models)
+- 05 → 08 (Linux database depends on Linux models)
+- 06, 07, 08 → 09, 10, 11 (feed parsers need database layer)
+- 09 → 12 (iOS fetcher depends on iOS parser)
+- 10 → 13 (Android fetcher depends on Android parser)
+- 11 → 14 (Linux fetcher depends on Linux parser)
+- 12, 13, 14 → 15, 16, 17 (state management depends on fetchers)
+- 15 → 18, 21, 24, 27, 30 (iOS services depend on state management)
+- 16 → 19, 22, 25, 28, 31 (Android services depend on state management)
+- 17 → 20, 23, 26, 29, 32 (Linux services depend on state management)
+- 30, 31, 32 → 33, 34, 35 (UI integration depends on all stores)
+- 36, 37, 38 → 39 (integration tests depend on unit tests)
+- 39 → 40 (optimization comes after testing)
