## 🚀 Quick Start

### Installation

```bash
pip install stinger
```

### Basic Usage

```bash
# Scan a single contract
scorpius scan contract.sol

# Scan entire directory with PDF report
scorpius scan contracts/ --report pdf

# Scan with specific severity filter
scorpius scan contracts/ --severity High --format json

# Generate detailed HTML report
scorpius scan . --recursive --report html

# Predict vulnerability for specific code
scorpius predict vulnerable_function.sol

# View scanner statistics
scorpius stats

# Export learned patterns
scorpius patterns --export rules.json
```

### Python API

```python
import asyncio
from scorpius import ScorpiusScanner

async def scan_contract():
    scanner = ScorpiusScanner()
    await scanner.initialize()
    
    with open('contract.sol', 'r') as f:
        contract_code = f.read()
    
    result = await scanner.scan_contract(contract_code)
    
    print(f"Found {result['total_found']} vulnerabilities")
    for vuln in result['vulnerabilities']:
        print(f"- {vuln['type']} ({vuln['severity']}) - {vuln['confidence']:.2f}")

asyncio.run(scan_contract())
