One of the most important things to have for any operating system is good documentation. Linux is no exception.
Although there is no “box” for Fedora, so there can be no out of the box documentation, there is a great deal of good documentation on line. The link below provides several documents for each of the Fedora releases from Fedora 7 through the current release of Fedora, whatever that might be at any given time. This includes Installation Guides, SELinux, information about Live Images, User’ Guides, a Quick Start Guide, Security and much more.
Be sure to use this excellent documentation as you install and use Fedora.
And Red Hat has its own set of excellent documentation which contains a great deal of the same information you would find for Fedora however it also provides detailed documentation for virtualization, Red Hat Satellite Server, Logical Volume Manager (LVM) administration, the Global File System (GFS) and much more. This documentation is located at:
Note that some of the Red Hat documentation, such as the Logical Volume Manager administration, also applies to Fedora. All of the Red Hat documentation applies directly to the equivalent version of CentOS.
All of the documentation for Fedora and Red Hat is available in multiple formats including EPUB, HTML and downloadable PDF files.
When you need high-quality vendor documentation these are the places to go.
A great deal of other documentation is available for both Fedora and Red Hat. There are many books available. I have included some of the ones I use the most and like the best in the Bibliography for the DataBooks.
