Server-Setup Help

Hey Guys,

I'm really into Extended Supply Servers and because the good ones (or the ones that have a good ping for me) are full or are causing my pc to get fps drops.
So I decided to get my own Server rolling.
I bought an Insurgency: Sandstorm Server on "".
I already checked some setup tutorials/guides but didn`t really get it...
Don't know if I'm just stupid or my english is not good enough, but I can't setup the server how I want it to be.
I really need some help with that.
I would appreciate, if someone with more knowledge of Insurgency Servers could help me ^^
