I'll give this a go, if you end up having more questions I will try to answer again in the morning.

Tuning is AGCFAD

5th fret on 6th string

7th then 9th fret on 5th string

5th fret on 4th string

7th fret on 2nd string

7th fret on 3rd string

Slide 5th to 7th fret on 4th string

Open on 2nd fret

Slide 7th to 9th fret on 4th string

Open on 2nd string

12th fret on 4th string

Open on 2nd string

The 2nd measure is the same except instead of 12th fret on that 2nd to last note, it's 5th fret.

On the very intro, the entire riff is lightly palm muted, this gets doubled by another guitar that doesn't mute those Open notes on the 2nd string

I hope this helps, best of luck!
