-
-Add a new line to the `providers` array:
-
-	Gloudemans\Shoppingcart\ShoppingcartServiceProvider::class

-And optionally add a new line to the `aliases` array:
-
-	'Cart' => Gloudemans\Shoppingcart\Facades\Cart::class,
-
 Now you're ready to start using the shoppingcart in your application.
 
 **As of version 2 of this package it's possibly to use dependency injection to inject an instance of the Cart class into your controller or other class**
