Katie Gray - Set Free Intro Chords & Tabs

soo this is my first tab.
i really wish someone new the chords to this song because i dont but i would like to learn.
i did manage to figure out the intro cause its pretty simple. But thats the only 
part of the song i no.

im pretty sure this is like 100 percent correct.

[ Tab from: https://www.guitartabs.cc/tabs/k/katie_gray/set_free_intro_tab.html ]
e|-------------------------------------|
B|-------------------------------------|
G|-------------------------------------|
D|-----2-------2------4-2--0-0-2-------| x3
A|---4---0--4----2--2------------------|
E|-2-----------------------------------|

on the fourth time you do the same thing but you stay open the D string.

thanks :)
