+``` php
+'aliases' => [

+        'App' => Illuminate\Support\Facades\App::class,
+        'Artisan' => Illuminate\Support\Facades\Artisan::class,

 Usage
 -----
 
 ``` php
 $url = app('bitly')->getUrl('https://www.google.com/'); // http://bit.ly/nHcn3
 ````
+
+Or if you want to use facade, add this in your class after namespace declaration:
+
+``` php
+use Bitly;
+```
+Then you can use it directly by calling `Bitly::` like:
+``` php
+$url = Bitly::getUrl('https://www.google.com/'); // http://bit.ly/nHcn3
