Installation in Lumen 5+

To set up Laravel Doctrine ACL in Lumen, we need some additional steps.

Install this package with composer:

composer require "laravel-doctrine/migrations"

After updating composer, open bootstrap/app.php and register the Service Provider after LaravelDoctrine\ORM\DoctrineServiceProvider::class

$app->register(LaravelDoctrine\Migrations\MigrationsServiceProvider::class);
