Beginners level assistance with DSC alarm/Alarmserver/Rasberry pi/EVL4

Hi Everyone!
I am pretty new to all of this tech and I need some help with this stuff. I have a Raspberry Pi3 the EVL4 is on the way but I am struggling with the Smartthings side of it. I have the DSC integration Smart App installed but where does the alarm server program or app go? I have found many Alarmserver links but for the life of me I cant figure out what goes where and some have plugins and updates etc. What OS and programs need to be loaded on the Rasberry Pi3 I have tried to watch videos and it seems everyone has a different approach. Any help will help me tons !! Chris
