 ## Background Information 
 This example demonstrates a simple OCR model built with the Functional API. Apart from combining CNN and RNN, it also illustrates how you can instantiate a new layer and use it as an "Endpoint layer" for implementing CTC loss. 
-This model uses subclassing so it's best if you could refer to [this guide](https://keras.io/guides/making_new_layers_and_models_via_subclassing/).
+This model uses subclassing, learn more about subclassing from [this guide](https://keras.io/guides/making_new_layers_and_models_via_subclassing/).
