Administrator is an administrative interface builder for Laravel. With Administrator you can visually manage your Eloquent models and their relations, and also create stand-alone settings pages for storing site data and performing site tasks.
Then publish the config file with php artisan config:publish Thirdsteplabs/administrator. This will add the file app/config/packages/Thirdsteplabs/administrator/administrator.php. This config file is the primary way you interact with Administrator.
Then finally you need to publish the package's assets with the php artisan asset:publish Thirdsteplabs/administrator command.
Since Administrator has switched over to Composer, you can no longer use php artisan bundle:install administrator or php artisan bundle:upgrade administrator. If you want to use Administrator with Laravel 3, you must switch to the 3.3.2 branch, download it, and add it in the /bundles/administrator directory and add this to your bundles.php file:
'administrator'=>array('handles'=>'admin', //this determines what URI this bundle will use'auto'=>true,),
