-Since this account is only for running Home Assistant the extra arguments of `-rm` is added to create a system account and create a home directory. The arguments `-G dialout,gpio` adds the user to the `dialout` and the `gpio` group. The first is required for using Z-Wave and Zigbee controllers, while the second is required to communicate with Raspberry's GPIO.

 Next we will create a directory for the installation of Home Assistant and change the owner to the `homeassistant` account.
