inmotion VPS Supervisor Install for Laravel Queue

Hi, our apps (Laravel 5.1) running on a Inmotion hosting (VPS) we want to use laravel queue, but how should we run the queue:listen or queue:work (i'm not sure exactly the difference between them)

it seems we may need to install supervisor at our server. can i install it myself ? or i need to contact inmotion to do this?

or please suggest us whats will be the best to run queue:listen in our server ..

Thanks
