+**Tips for best results:**
+- Use clear, well-lit photos
+- Include distinctive features (leaves, flowers, bark)
+- Avoid blurry or distant shots
+- One plant per photo
+
+### Step 3: Analyze
+- Click the **"Detect Plant Condition"** button

+
+## 📱 File Requirements
+
+- **Supported formats:** JPG, JPEG, PNG, GIF, WebP
+- **Maximum size:** 10MB
+- **Type:** Plant photos only
+
+## ❓ Common Questions
+
+**Q: What if my plant isn't recognized?**
+A: Try a different angle or ensure the photo shows clear plant features like leaves or flowers.
+
+**Q: Can I upload multiple photos at once?**
+A: Currently, only one photo at a time. Analyze them one by one.
+
+**Q: Is my photo stored?**
+A: No, photos are processed in memory and not permanently stored.
+
+**Q: How accurate is the identification?**
+A: The AI is powered by PlantNet, which has data on millions of plant species. Accuracy depends on photo quality and the plant's distinctiveness.
+
+## 🎯 Best Practices
+
+### For Better Identification:
+1. ✅ Take photos in natural daylight
+2. ✅ Include multiple plant parts if possible
+3. ✅ Ensure the plant is the main focus
+4. ✅ Avoid shadows and glare
+5. ✅ Take close-up shots of unique features
+
+### For Health Assessment:
+1. ✅ Show any problem areas clearly
+2. ✅ Include overall plant condition
+3. ✅ Photograph both healthy and unhealthy parts
+4. ✅ Capture leaf color and texture
+
+## 🔧 Troubleshooting
+
+**Issue: Upload button not working**
+- Check file size (must be under 10MB)
+- Verify file is an image format
+
+**Issue: "Detection failed" error**
+- Check internet connection
+- Try a different photo
+- Ensure photo shows plant clearly
+
+**Issue: Low confidence score**
+- Take a clearer photo
+- Focus on distinctive plant features
+- Try photographing flowers or leaves
+
+## 🌟 Pro Tips
+
+1. **Morning Light:** Take photos in morning light for best results
+2. **Multiple Angles:** Try different angles if first attempt has low confidence
+3. **Clean Lens:** Ensure your camera lens is clean
+4. **Stable Shot:** Hold camera steady or use a tripod
+5. **Background:** Use plain backgrounds when possible
+
+## 🎨 Understanding the Results
+
+### Confidence Score
+- **90-100%:** Very high confidence, likely accurate
+- **70-89%:** Good confidence, probably correct
+- **50-69%:** Moderate confidence, verify if possible
+- **Below 50%:** Low confidence, try another photo
+
+### Health Score
+The health score considers:
+- Visual appearance
+- Identification confidence
+- Species-specific health indicators
+
+### Care Tips
+Tips are customized based on:
+- Identified species
+- Current health score
+- Common care requirements
+- Potential issues detected
+
+## 📈 What's Next?
+
+After getting your results:
+1. Follow the care recommendations
+2. Monitor your plant's progress
+3. Take another photo in a week to track improvements
