Gcompute Where and how to download ?

So I got the zips from this site : https://github.com/notcake/gcompute
I just wanna know where do I unzip it so it can work on single player mode ?

Just put in addons folder like any other “legacy” addon

Also it’s a bad practice to use the “Download as Zip” option on github. You should really look into using a git client for this stuff
