+                    ## How to Use
+                    - **Image Upload**: Select a model, upload an image or provide a URL, and click "Detect" to see detected objects and image properties.
+                    - **URL Input**: Enter an image URL, select a model, and click "Process URL" to get results in JSON format.
+                    - **Models**: Choose from DETR (object detection or panoptic segmentation) or YOLOS (lightweight detection).
+                    - **Clear**: Reset all inputs and outputs using the "Clear" button.
+                    - **Errors**: Check the error box for any processing issues.
+                    
+                    ## Tips
+                    - Use high-quality images for better detection results.
+                    - Panoptic models (e.g., DETR-ResNet-50-panoptic) provide segmentation masks for complex scenes.
+                    - For faster processing, try YOLOS-Tiny on resource-constrained devices.
