78Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
79The one you choose depends on how much of the system you want to compile
80yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
81build the entire system from scratch. The <e>stage2</e> tarball is used for
82building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
83The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
84been built for you.

216The <e>Gentoo Alpha LiveCD</e> is a bootable CD which contain a
217self-sustained Gentoo environment. It allows you to boot Linux from the CD.

223The <e>Gentoo Alpha LiveCD</e> is a small, no-nonsense, bootable CD which sole
224purpose is to boot the system, prepare the networking and continue with the
225Gentoo installation. It does not contain any stages (or, in some cases, a
226single stage1 file), source code or precompiled packages. For example the
227alpha variant of this LiveCD can be found in the
228<path>releases/1.4_rc1/alpha</path> subdirectory and is called

245The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
246self-sustained Gentoo environment. They allow you to boot Linux from the CD.
247During the boot process your hardware is detected and the appropriate drivers
248are loaded. They are maintained by Gentoo developers.
249</p>
250
251<p>
252All Installation CDs allow you to boot, set up networking, initialize your
253partitions and start installing Gentoo from the Internet. We currently provide
254two Installation CDs which are equaly suitable to install Gentoo from, as long
255as you're planning on performing an Internet-based installation using the
256latest version of the available packages.
257</p>
258
259<p>
260If you wish to install Gentoo without a working Internet connection, please use
261the installation instructions described in the <uri
262link="2005.0/index.xml">Gentoo 2005.0 Handbooks</uri>.

271 The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
272 sole purpose is to boot the system, prepare the networking and continue
273 with the Gentoo installation.
274 </li>
275 <li>
276 The Gentoo Universal Installation CD, a bootable CD with the same abilities
277 as the Minimal Installation CD. Additionally, it contains a stage1 and
278 several stage3 tarballs (optimized for the individual subarchitectures).
279 </li>
280</ul>
281
282<p>
283To help you decide which Installation CD you need, we have written down the
284major advantages and disadvantages of each Installation CD.

246 331The Universal Installation CD is called <c>install-x86-universal-2005.0.iso</c>

333to install Gentoo, and you can even use it to install Gentoo without a working

368that allows you to easily and quickly install additional applications (such as

410Another way to check the validity of the downloaded file is to use GnuPG to
411verify the cryptographic signature that we provide (the file ending with
