Server Nitty Gritty (Don't Worry About This)
We run our instance via Docker, a container software, and deploy it via images built via Docker Hub. The site itself runs from the "stable" tag: https://hub.docker.com/r/pluralcafe/mastodon/builds/
If you want to know what files run Plural Cafe the server, it's all here: https://github.com/pluralcafe/utils/tree/master/deploy
The shell script in there (setup-mastodon.sh) is a setup script to install everything from fresh if you want to play around with it yourself.
