 Active Record models are placed under the `app/models` directory by default. But
 you may want to organize your models by placing similar models under their own
 folder and namespace. For example, `order.rb` and `review.rb` under
-`app/models/product` with `Product::Order` and `Product::Review` class names,
+`app/models/books` with `Book::Order` and `Book::Review` class names,
 respectively. You can create namespaced models with Active Record.
