How to start up

[MR ZenWiz <mrzenwiz gmail com>]

I've been looking for some reference that will tell me how to use
ostree on a fresh installation (Xubuntu 20.04 VM) to deploy the OS on
that same machine.

So far I have found nothing like this.  All the documentation I've
seen seems to presuppose that I'm already familiar with a fairly
detailed technical knowledge of how the ostree repo is after it has
been set up, not how to set it up to fold-in the current running OS to
be the next (and moving forward) system default boot OS.

Can someone tell me where I might find this?  A step by step
instruction guide would be best (I'm an ostree rank novice, though
I've been developing software in UNIX/Linux for over 30 years).

Many thanks for your consideration.
