I referenced Google domains because that's what a lot of people are currently using. I thought about not mentioning it but it doesn't really matter which registrar you're using at the end of the day.

I chose Debian 11 for stability and compatibility with other user friendly hosting options, such as Yuno Host. As far as I'm aware, Yuno does not currently support 12 yet. (I don't recommend installing Lemmy through YH as it's on an ancient version and doesn't support photo uploads nor phone apps)

You do not need to use a static IP with cloudflare as long as you use 'localhost' instead of 192.xxx.x.xx because cloudflared (the cloudflare tunnel software) runs on the server locally, and can detect changes in IP.

I'll probably add screenshots if I get a second request for them. Screenshots require performing the actions proper and I didn't have a test environment ready when I wrote this. Might make a video and add screenshots from that, we'll see.

I found your suggestions incredibly helpful! Thank you for taking the time to share them with me!
