FediBooks is currently unfinished - many functions don't work yet, and future updates may make major, breaking changes. I don't recommend self-hosting it yet unless you're willing to work through the potential growing pains.
1. Install ``python3`` and ``mariadb`` or ``mysql``. If you're installing on Windows, make sure to check "Add Python to PATH" during Python installation.
If this doesn't work, try using ``pip`` instead. If it still doesn't work, you might have to install an additional package (for example, ``python-pip`` on Arch Linux).
