-# FastAPI Application
+# Generic REST API Service
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A RESTful API built with FastAPI and SQLite, providing endpoints for user and item management.
+
+## Features
+
+- User management (create, read, update, delete)
+- Item management (create, read, update, delete)
+- SQLite database with SQLAlchemy ORM
+- Alembic migrations
+- OpenAPI documentation (Swagger UI)
+- Password hashing with bcrypt
+- Health check endpoint
+
+## Requirements
+
+- Python 3.8+
+- FastAPI
+- SQLAlchemy
+- Alembic
+- Uvicorn
+- Pydantic
+- Other dependencies as listed in requirements.txt
+
+## Project Structure

+
+## Installation
+
+1. Clone the repository:
+
+```bash
+git clone <repository-url>
+cd genericrestapiservice
+```
+
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+3. Run database migrations:
+
+```bash
+alembic upgrade head
+```
+
+## Running the Application
+
+Start the application using Uvicorn:
+
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+The API will be available at http://localhost:8000.
+
+## API Documentation
+
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+
+## API Endpoints
+
+### Health Check
+- `GET /health` - Check the API health status
+
+### Users
+- `GET /api/v1/users/` - List all users
+- `POST /api/v1/users/` - Create a new user
+- `GET /api/v1/users/{user_id}` - Get user details
+- `PUT /api/v1/users/{user_id}` - Update user information
+- `DELETE /api/v1/users/{user_id}` - Delete a user
+
+### Items
+- `GET /api/v1/items/` - List all items
+- `POST /api/v1/items/` - Create a new item
+- `GET /api/v1/items/{id}` - Get item details
+- `PUT /api/v1/items/{id}` - Update item information
+- `DELETE /api/v1/items/{id}` - Delete an item
+- `GET /api/v1/items/user/{owner_id}` - List all items owned by a specific user
+
+## Development
+
+### Database Migrations
+
+Generate a new migration:
+
+```bash
+alembic revision -m "description"
+```
+
+Apply migrations:
+
+```bash
+alembic upgrade head
+```
+
+Revert migrations:
+
+```bash
+alembic downgrade -1
+```
