The manual install guide is good to go, but the stage4 install guide is still being worked on.
Note: Some people who work in professional audio and want to use Linux dual-boot with Windows. This is not a problem - just install Windows first, if you haven't done so already. If you install Windows after installing Linux, you will screw up your bootloader and have to deal with reinstalling it. GRUB2 can boot you into Windows. Windows will not let you boot into Linux.
SystemRescueCD is the recommended way to manually install Gentoo Studio. SystemRescueCD provides a 64-bit boot option (required for Gentoo Studio) and uses Xfce as its desktop environment. SystemRescueCD also supports various wireless cards, which makes installing on a laptop, without a hard line, easier. With SystemRescueCD, you should be able to boot up and get online in short order to begin installing from a graphical environment that runs quickly from your DVD drive. In addition, SystemRescueCD is a great way to boot your machine to chroot into a non-working system to troubleshoot.
Before booting with SystemRescueCD, you need to know if your machine is BIOS or UEFI. You'll need to enter your machine's setup menu. Check for Secure Boot and turn that off if you have it, or you won't be able to boot SystemRescueCD. If you have UEFI and legacy compatibility, you will not need legacy compatibility, but if you turn it on anyway, set it to load UEFI before BIOS. SystemRescueCD will boot in UEFI, and this is necessary to prepare your system to boot in UEFI.
C) Standard 64bit kernel (rescue64) with more choice...
1. SystemRescueCd with default options
If SystemRescueCD booted in UEFI, you will see a basic GRUB menu. In this case, the default option #1 is the correct option.

Note: Generally, if you are not instructed to do something, don't do it unless you know what you're doing. For example, you see something in the kernel config and you wonder if you should enable it. Don't, unless this guide mentions that specific item. Also please keep in mind that while this guide is based very much on the standard handbook, it will differ from it. So please don't add or skip a step because it is or is not in the handbook but is or is not not here. Those additions and ommissions are intentional. In other words, if you want a Gentoo install for professional audio work, THIS is your handbook now.
Incidentally, this guide is the way the stage 4 tarball was built. Of course, the tarball takes things much further than a basic setup.
