-Package provides a simple trait that allows to use/generate UUIDs as IDs in Laravel models.
+Package provides a simple way to use strongly typed enum objects with Laravel models. It utilizes Laravel's custom
+casting mechanism.
 
 ## Installation
 To install the package via Composer, simply run the following command:
-```
-composer require desmart/laravel-uuid-id
+
+```bash
+composer require desmart/laravel-enum
 ```
 
 ## Usage
 
+Create an enum class that extends `DeSmart\Laravel\Enumeration`. Then, simply define all possible values in form of
+class constants:
+
+```php
+class Character extends DeSmart\Laravel\Enumeration
+{
+    const GOOD = 'good';
+    const EVIL = 'evil';
+    const SOMETIMES_GOOD_SOMETIMES_EVIL = 'sometimes_good_sometimes_evil';
+}
+```
+
+In Laravel model:
+
+```php
+class Hero extends Model
+{
+    /**
+     * @var array
+     */
+    protected $casts = [
+        'character' => Character::class,
+    ];
+}
+```
+
+That's it.
+
+```php
+$hero = new Hero(['character' => Character::EVIL]);
+
+dump($hero);
+// Hero {#293
+//  ...
+//  #casts: array:1 [
+//    "character" => "Character"
+//  ]
+// ...
+//  #attributes: array:1 [
+//    "character" => "evil"
+//  ]
+// }
+
+dump($hero->character);
+// Character {#296
+//  -value: "good"
+// }
+```
