I actually just tried doing this with AlexGIF last night. We downloaded the code from git and the process of getting it going was a bit more complicated than I anticipated so It will be worked on and improved eventually.
For now, you need to download it, then place all the lib_ folders in your mod directory.
Remove Sara's simple survival folder from the mod directory.
If you want to use git with it still, then preserve the .git folder in the Sara's Simple Survival folder too and move it into the mods folder too.
The config files arent mods, they are meant to showcase how i have the game configured in my config files so you can delete those if you dont want to use them but some of the mods in the git repository are not turned on for various reasons.
