please can this be done in Slim?

Alex, can you do a quick video on setting up Supervisor on a dedicated server type system OR how to setup a cronjob for it that is reliable. Reason I say reliable is that the info I found online for a cronjob situation indicates that the process hangs and doesn't work all the time. Something that I don't quite understand when installing Supervisor is should it be setup under the root of the server or is it setup inside the directory of the website I want to run it for? I think I understand most of the rest of the setup but that part is confusing.
