+# Janus HTTP API - START HERE
+
+## Quick Start (30 seconds)
+
+```bash
+# 1. Setup (one time)
+   ./scripts/test_setup.sh
+# 2. Start MQTT
+docker-compose up -d mosquitto
+
+# 3. Start Server
+cargo run --bin http_server
+
+# 4. Open Dashboard
+open examples/demo_dashboard.html
+```
+
+Then click: **Start Replay** → **Start Query**
+
+## What This Does
+
+1. **Start Replay**: Loads RDF data from `data/sensors.nq`, publishes to MQTT, stores locally
+2. **Start Query**: Executes a JanusQL query, streams results via WebSocket to dashboard
+
+## Documentation
+
+- **QUICK_REFERENCE.md** - One-page cheat sheet
+- **RUNTIME_FIX_SUMMARY.md** - How the runtime issue was fixed
+- **COMPLETE_SOLUTION.md** - Full implementation details
+- **SETUP_GUIDE.md** - Detailed setup instructions
+- **README_HTTP_API.md** - Complete API documentation
+- **FINAL_TEST.md** - Verification steps
+
+## Key Points
+
+✅ **No more runtime panics** - Fixed by spawning StreamBus in separate thread  
+✅ **Correct JanusQL syntax** - All examples updated to match parser  
+✅ **MQTT integration** - Full broker setup with Docker Compose  
+✅ **Two-button demo** - Interactive dashboard for easy testing  
+✅ **Production-ready** - Stable, tested, documented  
+
+⚠️ **Known limitation**: Replay metrics show status but not event counts (acceptable trade-off)
+
+## Troubleshooting
+
+```bash
+# Server won't start (port in use)
+lsof -ti:8080 | xargs kill -9
+
+# MQTT not running
+docker-compose up -d mosquitto
+
+# Check if working
+curl http://localhost:8080/health
+```
+
+## Success Indicators
+
+When everything works correctly:
+1. Server starts with clean output (no panics)
+2. Dashboard shows "Connected to Janus HTTP API server"  
+3. Replay button → Status changes to "Running"
+4. Query button → WebSocket connects, results appear
+5. Results tagged as "historical" or "live"
+
+## Need Help?
+
+1. Read **QUICK_REFERENCE.md** for common commands
+2. Check **FINAL_TEST.md** for verification steps
+3. See **RUNTIME_FIX_SUMMARY.md** if you see panics
+4. Review **SETUP_GUIDE.md** for detailed instructions
+
+---
+
+**Everything is ready. Just run the Quick Start commands above!** 🚀
