Lemmy newbie looking for configuration advice

I have been looking for a simpler guide to configure this UI component, photon for my lemmy instance(first turkish lemmy instance, possibly) but I wasn't able to figure it out.

I'm not much of a devops-savvy person being the software dev I am, most likely I should change the reverse proxy setting but again, I don't have the faintest idea about it. Any suggestions or guides?
