Go to this page:

and start with the beginner's section.
Any questions, you can post them here or in the beginner's forum and someone will answer you.
I started with nothing - and I've still got most of it left.
Did you know that the word "gullible" is not in any dictionary?

Greybeard has it spot on.
You need to start at the very beggining.
Use the lessons here and maybe pick up a beginners lesson book.
Some of the material you will obviously breeze through but you will learn the stuff you missed. In particular reading and understanding music.
