Nightforce zero stop adjustment help

[Brush buster]

I have an NX8 4-32 that is zeroed at 200yards. I'd like to adjust my zero down to 100 yards. How do I change the zero stop to move it down? I've watched videos and seen the instructions but somehow I'm still confused.
Thanks

It's very easy
Take the elevation cap off
Loosen the 4 screws on top clutch
Rotate the top clutch counter clockwise
1/2 turn
Tighten down the four clutch screws
Put your elevation cap back on
Turn the elevation down until you have a 100yds zero.
Follow zero lock instructions
