I believe this is a 2/2 time signature -althought I could be mistaken..
It is an awesome song overall written in key of A minor.

Here we go with the chords:


For the intro:
	Strum the A minor chord with root on 6th note the first time, the second 
run go for the Am chord again, but this time an octave higher -root on 12th fret, 5th string.


Am                                               G

Em - G - Am
          Remember the mount Zion
Em - G - Am
          Please remember the mount Zion
Em - G - Am
          You must remember the mount Zion
Em                 G
  Yo grown in my heart

    Am


And that's about it, the struming is ridiculously easy, best if you strum upwards. 
The only time it changes is during Em and G chords that it is strummed twice during each beat.
