I proposed you to write down these steps as a starting point for
improving the manual to turn it into a patch (for the Manual or the
Cookbook); this is actionable.  Otherwise say « improve this part of
the manual » is not constructive; this is not actionable.  I (and
probably others) do not see what could be improved in this area so it
appears to me hard to improve something that I do not know what. :-)

Last, the manual says:

        This option requires familiarity with GNU/Linux, with the shell,
        and with common administration tools. If you think this is not
        for you, consider using the guided graphical installer.

<https://guix.gnu.org/manual/en/html_node/Manual-Installation.html>

Therefore, it appears to me expected that this section provides only
command hints and not one by one step to complete all the process.
Other said, I expect that user who does not know how to fully complete
will run the Graphical Installer.  Does Nix have a Graphical
Installer?


All the best,
