+
+### 🛠️ Troubleshooting
+
+**Q: The detection is very slow. Why?**  
+A: Computer vision is computationally intensive. Speed depends on:
+- Your hardware (GPU is faster than CPU)
+- Image size (larger images take longer)
+- Server load
+
+Typical processing: 2-10 seconds per image.
+
+**Q: "No trash detected" but I can see trash in the image?**  
+A: Try:
+- Taking a clearer, better-lit photo
+- Getting closer to the trash
+- Ensuring items are visible (not hidden)
+- Adjusting camera angle
+
+If issues persist, the model may need retraining on similar images.
+
+**Q: How do I report a bug or suggest a feature?**  
+A: Check the project repository for:
+- Issue tracker
+- Contribution guidelines
+- Contact information
+
+---
 
-**Q: How can I contribute or report issues?**  
-A: Check the project repository for contribution guidelines and issue tracking.
+### 🌍 Making an Impact
+
+**Q: Does this really help clean up trash?**  
+A: This tool provides:
+- **Documentation** for authorities
+- **Evidence** of recurring problems
+- **Data** to support cleanup requests
+- **Organization** for community action
+
+Real cleanup requires human action, but this tool makes that action more effective and data-driven!
+
+**Q: Can I contribute to this project?**  
+A: Yes! This is an open-source hackathon project. Ways to contribute:
+- Test and report bugs
