Hey this probably isn't the real way 
to play it but it sounds kinda like the intro.
You might be able to figure out the rest on your own.
You just play this on two strings.
This sounds if better if you play it down
about in an inch below the sound hole.
When you play that first fifth fret on the D string 
it adds the layering in the song that that the lead 
guitar does in the song.
You can probably figure out the strumming pattern by yourself.
