## 🚀 Deployment Readiness

### Git Repository
- [x] Git initialized
- [ ] Remote added (add your HF Space URL)
- [ ] All files committed
- [ ] Ready to push

### Hugging Face Spaces
- [ ] Space created on HF
- [ ] SDK set to "Gradio"
- [ ] Hardware set to "ZeroGPU"
- [ ] Repository connected

### Testing Plan
- [ ] Deploy to HF Spaces
- [ ] Wait for build (~5 min)
- [ ] Test sign detection
- [ ] Test voice input
- [ ] Verify GPU allocation
- [ ] Check error handling

---

## 📊 Expected Results After Deployment

### Build Process (5-10 minutes)
1. ✅ Install dependencies
2. ✅ Load app.py
3. ✅ Initialize Gradio
4. ✅ Load YOLO model
5. ✅ Ready to use

### First Run
1. User opens Space
2. Models load on first use (~30s)
3. GPU allocated on demand
4. Inference completes (<2s)
5. GPU automatically released

### Performance
- **Startup**: ~30 seconds
- **Detection**: 1-2 seconds
- **GPU Memory**: 2-3 GB
- **Response Time**: <2 seconds

---

## 🐛 Common Issues & Solutions

### Issue: Models not loading
**Solution**: Check Space logs, ensure best.pt exists

### Issue: GPU not allocated
**Solution**: Verify ZeroGPU is selected in Space settings

### Issue: Build fails
**Solution**: Check requirements.txt versions, review build logs

### Issue: Slow inference
**Solution**: Ensure GPU is being used, check @spaces.GPU decorator
