# 🎬 Start Here - 5-Minute Overview

## What Changed
Your xAPI integrator was:
- ❌ Client-side only (run in browser)
- ❌ 3 modes (Timeline, Quiz, Minimal)

Now it is:
- ✅ Server-side Node.js application
- ✅ 4 modes including AI-powered
- ✅ Secure, production-ready
- ✅ Fully documented
- ✅ Ready to deploy

## The New 4th Mode: AI Agent

Instead of predefined tracking:
```
Before: Pick a mode → Fixed tracking code
After:  Pick AI Agent → Gemini analyzes YOUR content → Custom tracking code
```

**Result:** Smart, adaptive tracking tailored to your specific interactive content.

## Get Started (Choose One)

### Option A: Test Locally (15 min)
```bash
# 1. Get free Gemini API key (2 min)
Visit: https://makersuite.google.com/app/apikey
Click: "Create API Key"

# 2. Setup (5 min)
cp .env.example .env
# Paste API key into .env
npm install

# 3. Run (3 min)
npm run dev
# Open http://localhost:3000 in browser
```

### Option B: Deploy to Production (30 min)
```bash
# 1. Get Gemini API key (from Option A)

# 2. On your server
Follow DEPLOYMENT.md exactly

# 3. Result

# 🤖 Understanding the AI Mode

### How It Works
1. You upload a ZIP with your interactive content
2. Click "AI Agent Mode"
3. System sends content to Gemini Pro
4. Gemini analyzes it and generates xAPI tracking
5. You download the enhanced ZIP

### Why It's Better
- **Automatic:** No manual configuration
- **Smart:** Understands your content type
- **Free:** Uses Gemini's free tier
- **Flexible:** Works with any interactive content
- **Adaptive:** Learns from content structure

### Example
```
Quiz with radio buttons, checkboxes, score
         ↓
    AI analyzes
         ↓
    Generates tracking for:
    - Each question
    - Each answer
    - Time per question  
    - Final score
    - Navigation patterns
         ↓
    Injects into your HTML
         ↓
    You download ready-to-use ZIP
```

# 🆘 Common Issues

### "API key not set"
→ Make sure .env file exists with GOOGLE_API_KEY

### "Port 3000 in use"
→ Change PORT in .env or kill the process

### "File upload fails"
→ Must be .zip with index.html at root or one level deep

### "AI mode not working"
→ Check API key is valid (test at makersuite.google.com)

See README.md troubleshooting section for more help.
