It's hard to write down the timing of the song but listen to it and you'll get it
This is the main part (and Intro), so when I write 'D', it means go back to playing this:
D Dsus4
e|--2-2-2-2-2--2-2-2-3-2-|
B|--3-3-3-3-3--3-3-3-3-3-|
G|--2-2-2-2-2--2-2-2-2-2-|
D|--0-0-0-0-0--0-0-0-0-0-|
A|-----------------------|
