 You should start by setting up your eloquent model.  
 **Important:** You should read the [Instructions](https://github.com/glorand/laravel-model-settings#update_models) of the `glorand/laravel-model-settings` to find out how to do this.

+### Settings within your existing Resouce
+
+The settings can also be used in your existing resource.
+If, for example you have a school model with the settings `color` and `can_add_students`.
+
+```php
+namespace App\Models;
+
+use Glorand\Model\Settings\Traits\HasSettingsField;
+
+class School extends Model
+{
+    use HasSettingsField;
+
+    public $defaultSettings = [
+        'color' => '#ff0000',
+        'can_add_students' => true,
+    ];
+}
+```
+
+You can then use the provided macro `isModelSetting()` to use these settings inside your resource.
+
+```php
+namespace App\Filament\Resources;
+
+class SchoolResource extends Resource
+{
+    public static function form(Form $form): Form
+    {
+        return $form
+            ->schema([
+                Forms\Components\ColorPicker::make('settings.color_1')
+                    ->isModelSetting(),
+                Forms\Components\Toggle::make('settings.can_add_students')
+                    ->isModelSetting(),
+            ]);
+    }
+}
+```
+
+In case you changed your column name for the settings, you should provide that to `isModelSetting` as a prefix.
+
+```php
+Forms\Components\Toggle::make('school_stuff.can_add_students')
+    ->isModelSetting('school_stuff'),
+```
