         ## Welcome to the Object Evolution Generator!
-
         This app allows you to generate visualizations of how an object, like a bicycle or a car, may have evolved over time. 
         It generates images of the object in the past, present, and future based on your input.
-
-        ### How to use:
-        - Enter the name of an object (e.g., "bicycle", "car", "phone").
-        - Click "Generate Evolution" to generate the evolution of the object across three time periods: past, present, and future.
-        - View the generated images and a GIF showing the evolution of the object.
-
-        ### Example:
-        Try entering an object name like "car" and see how it has evolved!
+        
+        ### Default Example: Evolution of a Car
+        Below, you can see a precomputed example of a "car" evolution. Enter another object to generate its evolution.
