Scaling Mastodon down

There is already a guide on scaling your Mastodon server up. This is a short guide on scaling your Mastodon server down.

I.e., maybe you want to run a small instance of <100 active users, and you want to keep your cloud costs reasonable. So you might be running everything on a single machine, with limited memory and CPU. (In my case, I was using a t3.medium instance with 2 vCPUs and 4GB of RAM.) How do you do this?

Note that I'm not a Ruby or Sidekiq expert, and most of this stuff I figured out through trial and error.
