[Koha] Installing Koha Demonstration Site

[Fadhili Ngalawa]

Hello Koha Friends,
I kindly request assistance on how to install and configure a Koha demo
site (for training purposes) that will be resetting itself at a particular
time every day.
Kindly refer to those ones listed in https://koha-community.org/demo/. I
have a Ubuntu 18.04 LTS server ready that can be accessed from the internet.
NB: I know how to install Koha in a production setup. It's only how to make
it a demo one that resets itself in a specified time.

Regards,
Fadhili
