The main riff of the song is this:
G|------0---------------|
D|----0---0-------------|
A|--0-------------------|
E|----------------------|
G|------0-0---------------|
D|----0-----0-------------|
A|--0---------------------|
E|------------------------|
You play this riff in the intro and as a verse.
To play the chorus, you play the main riff once and the rest you play this:
G|--------------0---------0-0-----|
D|------------0---0-----0-----0---|
A|----------0---------0-----------|
E|-0-1-2-4------------------------|
That is pretty much it!
Enjoy!
