Hello,

Very nice!

Maybe: “to correlate the multiple key updates.”

Maybe add: “This assumes that the Tor anonymous routing daemon is
already running on your system.  On Guix System, this can be achieved by
setting up @code{tor-service-type} (@pxref{Networking Services,
@code{tor-service-type}}).”

Apart from these minor nits, LGTM!
