# Quick Start

This guide will get you analyzing code in minutes.

## Basic Usage

### Analyze Everything

Run a full analysis on a directory:

```bash
mccabre analyze ./src
```

This will show:

- Cyclomatic complexity per file
- Lines of code metrics
- Detected code clones

### Complexity Only

To check only complexity metrics:

```bash
mccabre complexity ./src
```

### Clone Detection Only

To find duplicated code:

```bash
mccabre clones ./src
```

## Understanding the Output

### Terminal Output

Mccabre uses colors to highlight issues:

- **Green**: Low complexity (1-10)
- **Yellow**: Moderate complexity (11-20)
- **Red**: High complexity (21+)

Example output:
