+## Build Guide
+
+### Building Core
+
+```bash
+# Standard build
+cargo build --release
+
+# Platform-specific builds
+cargo build --release --target x86_64-unknown-linux-musl     # Linux x86_64
+cargo build --release --target aarch64-unknown-linux-musl    # Linux ARM64
+cargo build --release --target x86_64-apple-darwin           # macOS x86_64
+cargo build --release --target aarch64-apple-darwin          # macOS M1/M2
+cargo build --release --target x86_64-pc-windows-msvc        # Windows x86_64
+```
+
+Build artifacts: `target/[target-triple]/release/`
+
+### Building GUI
+
+```bash
+# 1. Build frontend
+pnpm -r build
+
+# 2. Build GUI application
+cd easytier-gui
+
+# Linux
+pnpm tauri build --target x86_64-unknown-linux-gnu
+
+# macOS
+pnpm tauri build --target x86_64-apple-darwin      # Intel
+pnpm tauri build --target aarch64-apple-darwin     # Apple Silicon
+
+# Windows
+pnpm tauri build --target x86_64-pc-windows-msvc   # x64
+```
+
+Build artifacts: `easytier-gui/src-tauri/target/release/bundle/`
+
+### Building Mobile
+
+```bash
+# 1. Install Android targets
+rustup target add aarch64-linux-android
+rustup target add armv7-linux-androideabi
+rustup target add i686-linux-android
+rustup target add x86_64-linux-android
+
+# 2. Build Android application
+cd easytier-gui
+pnpm tauri android build
+```
+
+Build artifacts: `easytier-gui/src-tauri/gen/android/app/build/outputs/apk/universal/release/`
+
+### Build Notes
+
+1. Cross-compilation for ARM/MIPS requires additional setup
+2. Windows builds need correct DLL files
+3. Check `.github/workflows/` for detailed build configurations
+
+## Development Workflow
+
+1. Create a feature branch from `develop`:
+   ```bash
+   git checkout develop
+   git checkout -b feature/your-feature-name
+   ```
+
+2. Make your changes following our coding standards
+
+3. Write or update tests as needed
+
+4. Use conventional commit messages:
+   ```
+   feat: add new feature
+   fix: resolve bug
+   docs: update documentation
+   test: add tests
+   chore: update dependencies
+   ```
+
+5. Submit a pull request to `develop`
+
+## Testing Guidelines
+
+### Running Tests
+
+```bash
+# Configure system (Linux)
+sudo modprobe br_netfilter
+sudo sysctl net.bridge.bridge-nf-call-iptables=0
+sudo sysctl net.bridge.bridge-nf-call-ip6tables=0
+
+# Run tests
+cargo test --no-default-features --features=full --verbose
+```
+
+### Test Requirements
+
+- Write tests for new features
+- Maintain existing test coverage
+- Tests should be isolated and repeatable
+- Include both unit and integration tests
+
+## Pull Request Guidelines
+
+1. Target the `develop` branch
+2. Ensure all tests pass
+3. Include clear description and purpose
+4. Reference related issues
+5. Keep changes focused and atomic
+6. Update documentation as needed
