+# Shopping List Server
+
+A simple Express.js server with SQLite database for managing shopping list items.
+
+## Features
+
+- CRUD operations for shopping list items
+- Automatic cleanup of checked items after 2 hours
+- SQLite database with Sequelize ORM
+- CORS enabled for frontend integration
+- RESTful API endpoints
+
+## Database Schema
+
+Each shopping item has:
+- `id`: Unique identifier (auto-increment)
+- `name`: Item name (required)
+- `amount`: Quantity/amount (default: "1")
+- `checked`: Boolean status (default: false)
+- `checkedAt`: Timestamp when item was checked
+- `date`: Creation date
+- `createdAt`: Auto-generated creation timestamp
+- `updatedAt`: Auto-generated update timestamp
+
+## API Endpoints
+
+### Shopping Items
+- `GET /api/shopping` - Get all shopping items
+- `GET /api/shopping/:id` - Get a specific shopping item
+- `POST /api/shopping` - Create a new shopping item
+- `PUT /api/shopping/:id` - Update a shopping item
+- `PATCH /api/shopping/:id/toggle` - Toggle checked status
+- `DELETE /api/shopping/:id` - Delete a shopping item
+- `DELETE /api/shopping/checked/all` - Delete all checked items
+
+### Health Check
+- `GET /api/health` - Server health check
+
+## Installation
+
+1. Install dependencies:
+   ```bash
+   pnpm install
+   ```
+
+2. Start the development server:
+   ```bash
+   pnpm dev
+   ```
+
+3. Or start the production server:
+   ```bash
+   pnpm start
+   ```
+
+The server will run on `http://localhost:3001` by default.
+
+## Environment Variables
+
+- `PORT`: Server port (default: 3001)
+- `NODE_ENV`: Environment mode (development/production)
+
+## Auto-cleanup
+
+Checked items are automatically deleted after 2 hours. The cleanup runs every 30 minutes.
