Hey I definitely commend you on the effort, but there are already 2 guides like this stickied in this forum, such as:
http://forum.ppcgeeks.com/showthread.php?t=9927
^which personally, I find to be a bit simpler and easier to read. Mainly due to the added numbering and additional links.
However, if you were able to write up a bigger guide, that would include how to use the ppcgeeks kitchen to make your own custom rom, specifically,
how to add in applications not included in any kitchen into a custom rom. That would help me out a ton ;P
Oh and you'd get a donation from me if you could explain in detail, how to not only add apps not included in the kitchen, but also how I can add those apps to my custom rom,
including how to load the serial / registration keys for my apps into a custom rom. That would be amazing
