Everyone has a different frame of mind that let's able to figure out some concepts better than others. There will certainly be people who need assistance.
As an example I install and run my own Drupal multisite server. However, there are plenty of people who even given step by step tutorials will still have difficulty. Yet maybe they are far better off at photography and taking good pictures than the skill required for a CMS.
A tutorial would be a fantastic idea to help people get started and where to look. So yes a tutorial would be a good idea.
