Process is at the top of the script file but is summarised as:

volume can be accessed by the script- Best to close Finder window for the DMG if one is loaded on mounting it
- Run the script to create a USB installer labelled as
{{MAC_OS_NAME}} Installer
- Use this USB installer to install Mac OS.
{{MAC_OS_NAME}} Installer
USB ready for use after running the script.DONE
