**Sphinx** is a platform that *renders RST files* to a web application
that is suitable for documentation. This guide provides a quick
installation guide for someone wanting to set up Sphinx on a VSP.
The install sphinx guide <https://www.sphinx-doc.org/en/master/usage/quickstart.html>
provides a good starting point, but we will make other changes to install
the latest version of Sphinx from PyPI.
The VPS setup for this workshop uses Docker image nginx\:latest
<https://hub.docker.com/_/nginx>, which uses Debian 10.
