Yes. Even the most complex technical setup can be accomplished by a non-technical person that can follow directions assuming that someone took the time to write clear and concise directions and included common caveats and troubles that one may run into and where to check for them. I have proven this many times over by having managers and directors that were non-technical follow my instructions. In the rare moments this breaks down, forums and chat rooms can be a very handy gap-filler and provides an indirect feedback loop to further improve documentation.
