Guide for auto deployment?

Great work with this plugin! Is there a guide for proper auto deployment?

I see the “Show Push-to-Deploy URL” and I guess I probably copy and paste this somewhere in Github so that it hits this url after push/update to trigger the update on my site but I am not exactly sure where to paste it and it would be nice to know from the creator how to handle this.

Further, I guess there is no way to just have my site monitor for updates and update automatically without this trigger? (Probably would be too resource intensive to keep checking all the time for the occasional updates and web hook method like this is better?)

Again, great work with this plugin. So many headaches related to deployment that this solves.
