The guide is aimed at developers working in virtual environments that
need to build or run several controller-0 setups (specifically, to
developers in need of running the Ansible bootstrap playbook multiple
times).
By configuring a local registry and downloading the needed images
beforehand, all subsequent installations can point to this local
registry to download images from it to the controller-0. Not going to
the internet everytime, devs are not subject to public registries' rate
limits.
