How do I create a config file for variables on character?

I am working in UE 4.7.6 and I have created a prototype game using the first person shooter (c++) template. I have been editing variables directly in the UE editor by writing UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Gameplay) before the given variables in the header file.

From what I have gathered, you can use UPROPERTY(Config) along with writing UCLASS(Config=Game) before the class declaration to create entry points in the config files, but I am not able to find the properties in the config files after doing so.
