Readme missing serialize and deserialize methods in ExternalConfigurationService example

[BlakeRhodes]

The example in the read me does not included overloads for the serialize and deserialize methods. I am not sure if this is intentional or if there is something missing. An explanation of what is happening would help here.

Hi @BlakeRhodes ,

Indeed this methods didn't overload anywhere. I think it's not completed feature from parent repository.

I plan to do standalone repository without fork parent, where I will clear all unnecessary from parent repository with global refactoring and documentation.

In any case, a serializer/deserializer to overload would be great.
