If you can, I suggest reaching out to the MediaWiki folks so they could add something like this to their docs. Let them know they can reach out to us for help if they need it. (We’re not users of MediaWiki, so best if a user reaches out).
Huh? That’s not complex at all. That’s your entire config to run your site, including TLS automation, compression, PHP, static files, and the rewrite for ?title=.
This is all stuff you can learn easily from the docs.
