This isn't only the intro, it is played again afer the first chorus (I think...).
It's really easy. Just listen for timing.

e-0---------------------------------------------------|
B---3-------------------------------------------------|
G------4-2-4-5-4-2-0----------------------------------|
D--------------------2-4-5-9-9-2-4-5-9-9--------------|
A-----------------------------------------------------|
E-----------------------------------------------------|

That's it. It's really easy. If I figure out the rest, I'll post it. Good luck!
