 PhonyRails will also check your model for a country_code method to use when normalizing the number. So `'070-12341234'` with `country_code` 'NL' will get normalized to `'317012341234'`.
 
+### Validations
+
 Use the Phony.plausible method to validate an attribute:
 
     validates :phone_number, :phony_plausible => true

 In your views use:
 
     <%= "some number string variable".phony_formatted(:format => :international, :spaces => '-') %>
 
+### Find by normalized number

+  So we use Home.normalize_number instead of PhonyRails.normalize_number. This way we can use the same default_country_code.
