82Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
83The one you choose depends on how much of the system you want to compile
84yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
85build the entire system from scratch. The <e>stage2</e> tarball is used for
86building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
87The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
88been built for you.

253The <e>Gentoo Alpha LiveCD</e> is a small, no-nonsense, bootable CD which sole
254purpose is to boot the system, prepare the networking and continue with the

256single stage1 file), source code or precompiled packages. For example the
257alpha variant of this LiveCD can be found in the

253All LiveCDs allow you to boot, set up networking, initialize your
254partitions and start installing Gentoo from the Internet. We currently provide
255two LiveCDs which are equaly suitable to install Gentoo from, as long as you're
256planning on performing an Internet-based installation using the latest version
257of the available packages.

261If you whish to install Gentoo without a working Internet connection, please use
262the installation instructions described in the <uri

264supported for the Alpha architecture though.
