I was going to recommend reading the sticky but some (mainly the book link) of the links don't work.
I would read this book.
And check out this tutorial.
There is another excellent one called something like elmo but I can't find it.
There is also Nigel's Tutorials.

But in our days electronic equipment are getting complicate. learning this is a must. Thank you for your time and info.
