Run Artisan command to set up Microweber multisite

So on a fresh install, I login to the root of Microweber and run (an edited version of this for my own site): php artisan microweber:install admin@site.com admin password storage/database1.sqlite microweber microweber nopass sqlite -p site_ -t dream -d 1 -c 1 --env=second-domain.com

However it just returns Could not open input file: artisan

Same if I just run PHP artisan list - is there a folder I need to go to first before I run that command?

To confirm I go - SSH root@[MY-IP] > Confirm Key and it shows root@microweber-ubuntu-s-[rest-of-info]:

I then run the command.

Thanks!
