## 📦 Installation

### Global Installation
```bash
npm install -g package-checker-cli
```

### Local Usage
```bash
npx package-checker-cli
```

## 🎯 Quick Start

1. Navigate to your project directory
2. Run dependency analysis: `checker check`
3. Get AI help: `checker help "describe your problem"`
4. Fix issues automatically: `checker fix`

## 🤖 AI-Powered Help

The standout feature - ask for help in natural language:

```bash
# Get help with any coding problem
checker help "my file is not running"
checker help "npm install fails with permission errors"
checker help "how do I optimize my webpack config"

# Auto-apply suggested fixes (skips confirmation)
checker help "fix my package.json dependencies" --auto
```

The AI can:
- ✅ Analyze your problem and suggest solutions
- ✅ Create new files with proper code
- ✅ Modify existing files to fix issues
- ✅ Delete problematic files
- ✅ Provide code examples and resources
- ✅ Always asks for your permission before making changes
