I don't like the official linux and fedora documentation.

My problems are:
- the official linux documentation looks like http://git.kernel.org/?p=linux/kerne...tation;hb=HEAD
- the official fedora documentation is like "from source to gui", but I downloaded, then installed, then ran fedora and want to start from what I see, because it's more familiar, then go deeper until installation from source, so I want a fedora documentation like "from gui to source".

Your motivations are:
- details are cool, but overviews are cool too
- do designers hate firefox and ubuntu?

The requirement is: linux and fedora are free and open source, so I want free and open source documentation.

Posts generally aren't deleted here. What you should do is respond to your post with the solution, so that others can benefit.

free and open source:
- linux documentation at http://tldp.org/
- fedora documentation at https://fedoraproject.org/wiki/Categoryocumentation

The smilie keeps laughing on me! Did I do anything wrong?

This is documentation for the kernel. Unless you want to know about how different parts of the kernel work, this is not what you want. You want to look at some kind of user guide. Rute is often suggested. Running Linux might also be good, if you want a physical book.

I've got no idea what you mean by this.

It's because you've got ":D" in that link. If you press the "Go Advanced" button and scroll down, there's an option that says "Disable smilies in text".
