## Prerequisites

- Python 3.8+
- virtualenv (recommended)

## Installation

1. Clone the repository:
   ```bash
   git clone <repository-url>
   cd <repository-directory>
   ```

2. Create and activate a virtual environment (optional but recommended):
   ```bash
   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   ```

3. Install dependencies:
   ```bash
   pip install -r requirements.txt
   ```

4. Initialize the database:
   ```bash
   alembic upgrade head
   ```

## Running the API

Start the API server with:

```bash
uvicorn main:app --reload
```

The API will be available at http://localhost:8000

## API Documentation

FastAPI automatically generates interactive API documentation:

- Swagger UI: http://localhost:8000/docs
- ReDoc: http://localhost:8000/redoc

## API Endpoints

## Development

### Database Migrations

After modifying models, create a new migration:

```bash
alembic revision -m "description of changes"
```

Apply migrations:

```bash
alembic upgrade head
```

Revert migrations:

```bash
alembic downgrade -1  # Go back one migration
```

### Code Quality

Run linting with Ruff:

```bash
ruff check .
ruff check --fix .  # Auto-fix issues
```
