There is an install manual for Kororaa 2005 Beta2-r1 here, and an installation manual for the Kororaa Live CD here.

Although this is explained in the install manual, here are some important notes about Beta2-r1:

There is one install CD, which has two environments on it. One is x86, the other is AMD64.

If you are wanting to install an AMD64 version of either Kororaa or Gororaa, then you need to type kororaa64 at the install CD boot prompt.

If you are wanting to install the x86 version of either Kororaa or Gororaa then you just need press enter (or wait for the timeout). This loads the default 32bit environment by envoking kororaa.

Once the install CD has booted, just follow the instructions, ie. run the command kororaa to begin the install :)

NOTE: The "x86" versions can ONLY be installed on a system with a CPU that has SSE instruction support. This means Pentium3 (Celeron must be Coppermine core) or later (as per info on front page).
The AMD64 versions can be installed on any AMD 64bit cpu, including AMD64, Sempron64, Turion and Opteron.

I would also like to let you know of some handy tools to help administrate your Kororaa system:

systemconfig (the main configuration menu you see when you first boot.)

genuser --simple (this command adds a user to your system)

genpass (generates a decent Linux password – good!)

gensetpass (reset a user's password)

chooseres (set your preferred resolutions in X)

choosekeymap (set your keyboard language)
