Hello,

The differences are explained in the wiki, mostly you'll chroot from another system to the futur location of Gentoo. Very few difference, you won't have the command "arch-chroot" and you'll have to setup the chroot with the bunch on command into the handbook.

Read it, several times if needed, and ask if you are blocked :).

don_cever,

Welcome to Gentoo.

Before you start on the handbook, you need one extra command.
As root, run
Code:
mkdir -p /mnt/gentoo


Other live systems do not provide that mount point, which is where your Gentoo install will be attached until it can boot.
The handbook assumes that
Code:
/mnt/gentoo
exists.

And just don't forget this:
Code:
 Warning
When using non-Gentoo installation media, this might not be sufficient. Some distributions make /dev/shm a symbolic link to /run/shm/ which, after the chroot, becomes invalid. Making /dev/shm/ a proper tmpfs mount up front can fix this:
root #test -L /dev/shm && rm /dev/shm && mkdir /dev/shm
root #mount --types tmpfs --options nosuid,nodev,noexec shm /dev/shm

Also ensure that mode 1777 is set:
root #chmod 1777 /dev/shm /run/shm


Which is anyway in the gentoo handbook. ^^
