+            ## How to Use This Tool
+            
+            1. **Upload an Image**: Click the upload button to select a radar image for analysis
+            2. **Generate Technical Report** (Optional): Check this box if you want a detailed technical report
+            3. **Analyze**: Click the Analyze button to process the image
+            4. **View Results**: 
+               - The detection visualization shows identified defects
+               - The analysis report provides a summary of findings
+               - The technical report (if requested) offers detailed metrics
+               - Charts provide visual representation of confidence scores and feature analysis
+            
+            ## About the Model
+            
+            This system uses PaliGemma, a vision-language model that combines SigLIP-So400m (image encoder) and Gemma-2B (text decoder) for joint object detection and multimodal analysis.
+            
+            ## Troubleshooting
+            
+            - If the analysis fails, try uploading a different image format
+            - Ensure the image is a valid radar scan
+            - For technical issues, check the console logs
