You’ll need something to actually host the site. I usually stick with nginx but that’s just preference. Once you get that running you can edit files for the site & start looking into some guides or tutorials for nginx.

I don’t recommend putting your site on the general internet. It’s just going to be attacked & can compromise your network. I have local web services but use a WireGuard VPN setup so that I can access when I’m not home, & not allow access to the internet.
