-                ### About
-                ChestAI uses advanced deep learning to detect pneumonia in chest X-rays.
-                
-                ### How to use
-                1. Upload a chest X-ray image (JPG/PNG)
-                2. Wait for the analysis
-                3. View the results and confidence score
-                
-                ### Note
-                This tool is for educational purposes only. Always consult healthcare professionals for medical advice.
