 Install `microbin` package from AUR and start/enable microbin systemd service. Systemd will start server on port 8080, which can be [changed](https://wiki.archlinux.org/title/Systemd#Editing_providd_units) via `systemctl edit microbin`. By default, almost all functions are enabled, and data is stored in `/var/lib/microbin`
