Having trouble installing the software

[Realrubr2]

Hey so i want to use your software to underclock my gpu, As far as i could get with reading your documentation is running ./scripts/build.sh, which got me this error: no bin target named amdguid-glium. Available bin targets: amdfan amdfand agc amdgui-helper amdmond amdports amdvold

But now im stuck i did a whole bunch of stuff just to get the amdfand, and that isnt even working properly so i think i must have fucked up.

DId i miss a step or do i really have to go into every file and all the README's to install this?

ps its my first week of using arch so maybe it is just one big skill issue
