+## 🚴‍ Route Model Binding
+
+If you enable the [middleware](#-use-middleware-to-update-app-locale) included in this package,
+you can use [Laravel's route model binding](https://laravel.com/docs/routing#route-model-binding)
+to automatically inject models with localized route keys in your controllers.
+
+All you need to do is add a `resolveRouteBinding()` method to your model.
+Check [Laravel's documentation](https://laravel.com/docs/routing#route-model-binding)
+for alternative ways to enable route model binding.
+
+```php
+public function resolveRouteBinding($value)
+{
+    // Perform the logic to find the given slug in the database...
+    return $this->where('slug->'.app()->getLocale(), $value)->firstOrFail();
+}
+```
+
+> **TIP:** checkout [spatie/laravel-translatable](https://github.com/spatie/laravel-translatable) for translatable models.

 ## 🗃 Cache Routes
 
 In production you can safely cache your routes per usual.
