## 🚀 Quick Start

### Installation

```bash
npm install @wia/xr-education
```

### Basic Usage

```typescript
import { XREducation } from '@wia/xr-education';

// Initialize XR session
const xr = new XREducation({
  apiKey: 'your-api-key',
  mode: 'immersive-vr',
  device: 'quest3'
});

// Create virtual classroom
const classroom = await xr.createVirtualClassroom({
  capacity: 30,
  features: {
    spatialAudio: true,
    whiteboard3D: true,
    breakoutRooms: true
  }
});

// Create chemistry lab
const lab = await xr.createVirtualLab({
  subject: 'chemistry',
  scenario: 'acid-base-titration',
  safetyLevel: 'high'
});

// Configure accessibility
xr.setAccessibility({
  visual: {
    subtitles: true,
    colorblindMode: 'deuteranopia'
  },
  motor: {
    seatedMode: true,
    snapTurning: true
  }
});

// Start learning session
const session = await xr.startSession({
