S6 Edge 5.1.1 G925F TWRP

Hi, I just got my S6 Edge 5.1.1 G925F about 2 weeks ago and I want to install XtreStoLite Deo-Mod Edition ROM. I've looked everywhere and I can't seem to find a good way to install TWRP recovery. I am rooted with UniKernel v8 on stock firmware. Any help would be greatfull to anyone that can help. Thank you.
