 ## Core Concepts
 
-* ``UITextField`` + ``ValidationRule`` go into  ```Validator``
-* ``ITextField`` + ``ValidationError`` come out of ```Validator``
-* ``UITextField`` is registered to ``Validator``
-* ``Validator`` evaluates ``ValidationRules`` sequentially and stops evaluating when a ``ValidationRule`` fails. 
-* Keys are used to allow field registration in TableViewControllers and complex view hierarchies
