 ### Annotating Decorators
-Decorators modify the behavior of a class or a function. Annotating decorators that leave the signature of the decorated function unchanged is straightforward with the help of generics.
+Decorators modify the behavior of a class or a function. Providing annotations for decorators is straightforward if the decorator retrains the original signature of the decorated function.
