+#### Under the Hood - How Anyfig Works
+The 'config_class' decorator adds some functions to the class e.g. __str__ that makes the class human readable. The decorator also registers the class with the anyfig module so that the 'setup_config' function can find it.
+
+The 'setup_config' function checks if the class specified in its 'default_config' argument is among the registered config-classes. If it is, a object is instantiated from the class definition and returned.

 ### Multiple Configs & Class Inheritence
 
 It's possible to have multiple config classes defined and select one at runtime. This could be useful if you e.g. have one default config and one for debugging.
 
-To select a config class, specify the config class in the input arguments with the --config flag
+To select a config class, specify the config class in the input arguments with the '--config' flag
 
 ```bash

-It's possible for a config class to inherit from any Python class as long as that class ultimately inherits from the Anyfig.MasterConfig class.

 ### Saving & Loading Configs
-Anyfig offers functions for both saving and loading a config. When saving, Anygif serializes the config object with the pickle module as well as a .txt file.
