I have heard from some people that they can't read tab and so I'd like to give an easy explanation, because if I have unusual chords here, I will indicate them in tab form.
So the easiest way to explain it, is to use a chord everybody knows. Lets use D.
You have 6 strings on your guitar. Tab notations begin with the lowest string. If you were to stand your guitar up, and look at where your fingers are placed to make a D chord, Starting with the lowest string, there is no finger there so it's a 0. No finger on the next string, so 0. No finger on the next, so again, 0.
Then on the next string you have a finger on the 2nd fret, so 2. The string over, finger on 3rd fret equals a 3, and on the highest string, finger on the 2nd fret equals a 2. So D, written in tab is 000232. Honestly, this is just SO much easier than making little graphs with dots, which are very hard to type.
