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!
