Hi! First comment on Lemmy (or any social media.) I run bubblesthebunny.com off this repo: https://github.com/BubblesTheBunny/lemmy

It requires Digital Ocean and Cloudflare, but it works pretty well. I use a pretty small VM though, so if you're looking for something that can handle 1000s of users you'll need to modify it slightly.

I yoinked a ton from the https://github.com/LemmyNet/lemmy-ansible repo, so if you want to roll your own that's a good place to start.
