You should install conky with lua support(conky-all in Debian,conky-lua in Archlinux) first.
Then:
git clone https://github.com/Moe-sushi/conkyrc
cd conkyrc
If you are using KDE:
cp kde/conkyrc ~/.conkyrc
If you are using Xfce4
cp xfce4/conkyrc ~/.conkyrc
For other desktop environments,please test it yourself.
Finally:
If your cpu has 4 cores:
cp 4cpus/clock.lua ~/.clock.lua
If your cpu has 8 cores:
cp 8cpus/clock.lua ~/.clock.lua
If your cpu has 12 cores:
cp 12cpus/clock.lua ~/.clock.lua
If your cpu has 6 cores:
Write it yourself please. I've wrote 12cpus myself.
