HURD install confusion

[arnuld]

i see there is a HURD install guide available here:
http://www.debian.org/ports/hurd/ and it says one needs to have an OS
already installed to install HURD.

now, i also see K14 CDs available and CD-1 is bootable.


i am getting confused on installation methods. when i need a
pre-installed OS to install HURD, for what purpose boot CD exists ?


[ i use Linux and have already installed it. i have some free space on
my ATA disk. i want to install and use HURD so that i can contribute
to its development]
