How do you read this guitar tab?

Each line represents a different string on the guitar. The bottom line in the series of six represents the low E string (the string that is the thickest and highest up when holding your guitar), the next line represents A, then D, and so on. The numbers represent the fret that you use on that string while plucking. So a 0 would mean you pluck it but don't fret it, 3 would mean you pluck it while holding fret 3.
