-Notice that without writing any GPU or 16-bit specific code, your models gain that capability by  
-using Lightning.    
+Notice a few things about this flow:   
+1. You're writing pure PyTorch... no unnecessary abstractions or new libraries to learn.   
+2. You get free GPU and 16-bit support without writing any of that code in your model.   
+3. You also get all of the capabilities below (without coding or testing yourself).
