I needed to deploy a child theme to a server for folks to check out the development. I went with a git remote to get the good stuff from git to quickly recover if (when) I break something.
On the server, I created a new directory:
$ sudo mkdir -p /var/repos/theme_name.git
The following instructions were predominantly sourced via this Apple Support Document.
With macOS, you can use a USB flash drive or other removable media as a startup disk from which to install macOS. These advanced steps are intended primarly for system administrators and others who are familiar with the command line.
The final executable command(s) are found within Section III. Final macOS Executable Commands labled as Full Example or Full Example w/Options. I personally use the w/Options command which include both the --nointeraction and &&say Installation commands.
