-This package provides a factory for creating the middleware, so we only need to
-wire it into our middleware pipeline.  Create and edit the file
-`config/autoload/middleware-pipeline.local.php` to read as follows:
-
-```php
-use PhpMiddleware\PhpDebugBar\PhpDebugBarMiddleware;
-use PhpMiddleware\PhpDebugBar\PhpDebugBarMiddlewareFactory;

+This package provides a config provider so only thing to do is add it into [ConfigManager](modular-layout.md):
 
-These changes will activate the toolbar in your application.
+```
+$configManager = new Zend\Expressive\ConfigManager\ConfigManager([
+    PhpMiddleware\PhpDebugBar\ConfigProvider::class,
+    new Zend\Expressive\ConfigManager\PhpFileProvider('config/autoload/{{,*.}global,{,*.}local}.php'),
+]);
+```
 
 > ### Use locally!
 >
-> You'll note that we specified the file `middleware-pipeline.local.php`, and
-> not `middleware-pipeline.global.php`. This ensures that the toolbar is only
-> enabled in the local environment, and not committed to your production
-> settings.
+> Remember to enable `PhpMiddleware\PhpDebugBar\ConfigProvider` only on your
+> development enviroments!
