-# FastAPI Application
+# Generic REST API Service
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A generic REST API service built with FastAPI and SQLite, providing endpoints for user management and item operations.
+
+## Features
+
+- User management (registration, authentication, profile management)
+- JWT-based authentication
+- Item CRUD operations
+- Database migrations with Alembic
+- Comprehensive API documentation
+- Health check endpoint
+

+
+## Setup
+
+1. Clone the repository
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+3. Run the application:
+
+```bash
+uvicorn main:app --reload
+```
+
+## API Documentation
+
+Once the application is running, you can access the automatically generated API documentation at:
+
+- Swagger UI: `http://localhost:8000/docs`
+- ReDoc: `http://localhost:8000/redoc`
+
+## Available Endpoints
+
+### Authentication
+
+- `POST /api/v1/users/token` - Login and get access token
+
+### Users
+
+- `POST /api/v1/users/` - Register a new user
+- `GET /api/v1/users/me` - Get current user profile
+- `PUT /api/v1/users/me` - Update current user profile
+- `GET /api/v1/users/` - List all users (requires authentication)
+- `GET /api/v1/users/{user_id}` - Get user by ID (requires authentication)
+
+### Items
+
+- `POST /api/v1/items/` - Create a new item (requires authentication)
+- `GET /api/v1/items/` - List all items (requires authentication)
+- `GET /api/v1/items/my-items` - List all items owned by current user (requires authentication)
+- `GET /api/v1/items/{item_id}` - Get item by ID (requires authentication)
+- `PUT /api/v1/items/{item_id}` - Update item (requires ownership)
+- `DELETE /api/v1/items/{item_id}` - Delete item (requires ownership)
+
+### Health Check
+
+- `GET /health` - API health status
+
+## Database Migrations
+
+To apply migrations:
+
+```bash
+alembic upgrade head
+```
