The Easiest way to do the intro riff is by making an Emaj bar chord 


Intro: 
e----------------------|
B-------9--------------|
G-----9---9------------|
D---9-------9-9--7-7---|
A-7---------9-9--7-7---|
E-----------7-7--5-5---| 2x

In the actual song she uses continues to use the intro riff for the verses, but if 
you want an easier way you can use these chords instead: 
Verse 1: 
E                    B         A      E                      B      A
