-Each method always returns a type of `void` and the output logic is solved via methods. The reason is that it is often necessary to pass a number of parameters and one output is not enough.
+Each method can return output either via `send` methods or directly as a type object. A more modern approach is to return the entire object, as this gives us type checking and the underlying basis for automatically generated documentation.

 When processing actions, it is a good idea to return success or error information:
