You're talking about a non-trivial technology that is predicated on a specific pre-existing skill set (google search skills help, but they'll just get you in over you head in this example). And as much as I'm a fan of stretch goals, I'd suggest beginners find something else to learn first, coming back around to this level of coding when you're better equipped, self-supporting, etc. Have to say, if someone has the skills to work w/CD, they're not likely looking for a 'simple tutorial'.

Same goes for beta tools....steer clear/re-align expectations if you're green, but at least appreciate that new stuff means rapid evolution...looking for 'simple tutorials' for fast moving content is usually counter-productive/unrealistic.
If it's (more) solid ground you're after, back your tools down and ramp your skills up.
