 ## Usage
 
-### Using the trait
+### Setup your enum
 
-The enum you create must implement BackedEnum, this interface allows the toArray and toJson functions from within IsBackEnum to be called on your
-enum.
+The enum you create must implement the `BackedEnum` interface and also use the `IsBackedEnum` trait.
+The interface is required for Laravel to cast your enum correctly and the trait is what gives your enum its superpowers.

+You may then access these localized values using the `->label()` or `::labelFor()` methods
+```php
+VolumeUnitEnum::MILLIGRAMS->label(); // "mg"

+If you do not specify a label in the lang file these methods will return the translation key e.g. `enums.\\App\\Enums\\VolumeUnitEnum.GRAMS`
 
 ### Meta data
 
 Adding metadata allows you to return additional values alongside the label and values.
