I think it's community maintained so the quality of individual tutorials can vary. The steps are divided into pages, and some tutorials offer different level of depth for the explanations (like novice and exbert).
Also these are written for Ubuntu, but most stuff can be adapted to Debian based distros, and beyond that, to any distro if one is familiar with the differences.
