+#### Implicit route model binding
+
+You can also use Laravels [implicit route model binding](https://laravel.com/docs/8.x/routing#implicit-binding) inside your controller to automatically resolve the model. To use this feature, make sure that the slug column matches the `routeNameKey`.  
+Currently, only some database types support JSON opterations. Further information about which databases support JSON can be found in the [Laravel docs](https://laravel.com/docs/8.x/queries#json-where-clauses).

+```php
+namespace App;
+
+use Spatie\Sluggable\HasSlug;
+use Spatie\Sluggable\SlugOptions;
+use Illuminate\Database\Eloquent\Model;
+
+class YourEloquentModel extends Model
+{
+    use HasTranslations, HasTranslatableSlug;
+
+    public $translatable = ['name', 'slug'];
+
+    /**
+     * Get the options for generating the slug.
+     */
