The intro is only hard at first because you gotta play 
the srings with your fingers instead of a pick.  It 
probably wont be hard for most of you, cuz im just a 
beginner.
This is my first tab so I did my best.

X=Don't play the string
/=slide up the string

e-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 
B-3-33/5-55/6-1-1-11-3-33/5-55/6-1-1-11 
G-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 
D-3-33/5-55/7-2-2-22-3-33/5-55/7-2-2-22 
A-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 
E-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 

That's it!
That same thing does repeat for most of the song, but 
I'm still workin on the rest.
Have fun!
