This book is a list of the primary components required to build a functional cPanel installation and a brief history of each component (Apache, MySQL, Unix or Unix-like OS).
The book is less than 100 pages and contains not one single 'how to' on any subject. There is no help for the cPanel/WHM administrator unless you absolutely have no idea where to start and there is no help for the end-user unless you needed to know what port cPanel and WHM normally use.
There is a very nice comparison chart showing a variety of Control Panels that would have been useful as part of a more comprehensive manual.
The book's type is so small that it is almost impossible to read.
This is not a manual.
I will be requesting a refund.
