I want to add a on/off switch to my pi 2 to correctly shut the pi down

This is the switch I want to add:

This guy in a Raspberry Pi kik group made this code for me

Edit - reproduced below:

#!/usr/bin/python3
 
import RPi.GPIO as g
from time import sleep
from subprocess import Popen
 
g.setmode(g.BCM)
g.setup(26,g.IN)
 
def p26_callback(channel):
  command = ['/usr/bin/sudo','poweroff']
  Popen(command)
  g.remove_event_detect(channel) # we've done it once, stop watching
  return
 
g.add_event_detect(26, g.FALLING, callback=p26_callback)
 
try:
    sleep(30)
finally:
    g.cleanup()

but he didn't explain how to wire it up. Also I have no idea how to add the code to the pi.

I'm running kali. I haven't tried to wire the switch or put the code in the pi because I do not know how to.
