you will find a huge collect of tutorials. The Debian project also has comprehensive tutorials.
So it may be a good idea to follow Debian. The Gentoo project has a good community forum -
I am sure trying to install Gentoo you will learn much. Don't bother yourself with desktop aimed distributions -
the only help you find there is a windowze-like help "click here, click there - a window will open, click right
button, press the ^] key" - completely useless.
