 ## 🧩 Add Middleware
 
-Add the middleware to the `web` middleware group in `app/Http/Kernel.php`.
+By default, the app locale will always be what you configured in `config/app.php`.
+To automatically update the app locale, you need to register the middleware in the `web` middleware group.
 Make sure to add it after `StartSession` and before `SubstituteBindings`.
 
 The order of the middleware is important if you are using localized route keys (translated slugs)!
 The session needs to be active when setting the locale, and the locale needs to be set when substituting the route bindings.
 
+### Laravel 11 and newer:
+
+Add the middleware to the `web` middleware group in `bootstrap/app.php`.
+
+```php
+// bootstrap/app.php
+->withMiddleware(function (Middleware $middleware) {
+    $middleware->web(remove: [
+        \Illuminate\Routing\Middleware\SubstituteBindings::class,

 # Upgrade Guide
 
+## Upgrading To 3.0 From 2.x
+
+### ➡ Minimum Requirements Updated
+
+Due to PHP and PHPUnit version constraints with Laravel 11, we dropped support for Laravel 7.x, 8.x and 9.x.
+
+- The minimum PHP version required is now 8.1
+- The minimum Laravel version required is now 10.0
+
+---
+
+### ➡ Re-register Middleware
+
+Laravel 11 no longer has a `app/Http/Kernel.php` to register middleware.
+This is now handled in `bootstrap/app.php`.
+
+🔸 **Actions Required**
+
+If you use Laravel 11, register the middleware in `bootstrap/app.php` as described in the README.
+
