+## Development Commands
+
+- `npm run dev` - Start development server with Turbopack (opens at http://localhost:3000)
+- `npm run build` - Build for production
+- `npm start` - Start production server
+- `npm run lint` - Run ESLint
+
+## Architecture Overview
+
+This is a Next.js 15 App Router application with TypeScript, implementing a shoe detection camera app with the following structure:
+
+### Core Architecture
+- **Frontend**: Next.js with App Router, React 19, TypeScript
+- **Styling**: Tailwind CSS v4 with shadcn/ui components (New York style)
+- **State Management**: React hooks with local storage for persistence
+- **UI Components**: Radix UI primitives with custom variants
+
+### Key Features
+- **Camera Integration**: WebRTC camera access with device selection and localStorage persistence
+- **Shoe Detection**: Simulated ML classification (currently returns random shoes from database)
+- **History System**: Local storage-based history with sidebar navigation
+- **Responsive UI**: Mobile-first design with overlay controls
+
+### File Structure
+- `app/` - Next.js App Router pages and layouts
+- `components/` - React components including shadcn/ui components
+- `lib/` - Business logic and utilities:
+  - `shoe-database.ts` - Static shoe data with type definitions
+  - `ml-classification.ts` - Mock ML detection logic
+  - `history-storage.ts` - Local storage management
+  - `utils.ts` - Utility functions (cn helper)
+
+### Component Architecture
+- Uses shadcn/ui component library with Radix UI primitives
+- Component variants managed with `class-variance-authority`
+- Icons from `lucide-react`
+- Custom components: `ShoeResultsPopup`, `HistorySidebar`
+
+### State Management Patterns
+- Camera state managed in main page component
+- Local storage for device preferences and history
+- Popup and sidebar state via boolean flags
+- No external state management library used
+
+### Configuration
+- TypeScript with strict mode and ES2017 target
+- ESLint with Next.js and TypeScript rules
+- Path aliases configured: `@/*` maps to project root
+- Turbopack enabled for faster development
