 A good example of clean architecture for a web application in Go.
 
 The **domain** folder is for **enterprise** business logic without any
 dependencies. These can be structs, interfaces, and functions.
 
-The **usecase** folder is for **application** business logic without any
-dependencies with the exception of the domain logic. These can be structs,
-interfaces, and functions. There is no usecase folder in this example.
+There is no **usecase** folder, but if there was, it would hold the
+**application** business logic without any dependencies with the exception of
+the domain logic. These can be structs, interfaces, and functions.
 
 The **adapter** folder should contain abstractions for the packages in the
 **lib** and **vendor** folders.
