[gentoo-user] Question on install

refering to the amd64 handbook, at gentoo.org  "downloading the stage tarball"  where it says "
Downloading the stage tarball
Go to the Gentoo mount point where the root file system is mounted (most likely /mnt/gentoo):
root #cd /mnt/gentoo" 

does that mean to change to where gentoo will be installed, or where the cd/dvd is mounted?  i'm using a gentoo live dvd.  seriously just trying to get a basic install to start with.  i ask because it doesn't seem reasonable (to my ignorant brain) to download to the ram drive created by the install dvd, if so then so, whatever works.  life is a learning process, those who've chosen to stop learning have chosen to stop living in a meaningful was.  i may trip sometimes, but i am always, always trying to learn, especially when it's "inconvenient".  thanks to all those intending to help.  

i have never cross posted, if this email appears anywhere other than "gentoo-user@×××××××××××.org please check the headers, it wasn't me, was never that ignorant nor arrogant.
