I remembered a member that said that we should have a flowchart, so regard my first try.
It does not involve things like spool pins (i did say 'basic'), and it certainly does not look professional, but it contains all the information that is needed to answer the first 3 questions that one asks around here.
(sorry that it makes you scroll side to side and all...

Some feedback please, on how i can make it appear more professional.
Personally, i'm thinking of also making a 'questions and answers' flowchart (for people that waltz in and ask about opening cars and etcetera).
Anyway, enjoy.
