... Hamburger Prince ... I was going to launch into a big rant here... but the
General Rules and
FAQs cover just about everything you have asked for here.
I'm just going to hope you're not trying to troll anyone here and ask that you read both (yes, they are actually very informative and should cover what you are missing here)...
Then come back to the topic here and see if you don't have a new perspective on things. If you still don't get it, maybe this place isn't for you.
If you really are still interested, there are a ton of tutorials in the
Tools, Resources and Linkage thread.
