I am sorry if this is an insanely dumb and idiotic question but how are you supposed to be actually installing this pack.
I came across this because someone mentioned it in a Discord server and wanted to install it, ran the main build python script and while that seemed to go through just fine there's none of the mods actually being downloaded and adding InstanceSync to get the mods won't work either since there's no minecraftinstance.json

For reference, I am using MultiMC if that could relate to the issue.

I guess going back to this, the easiest solution would probably be to have a CF upload that actually works because when downloading the server and managing to get the mods, it launches fine, the client on the other hand, crashes immediately.

And since you @Irgendwer01 are still making commits, I would assume you do have a working Client of the Pack available that you can publish to CF or make a better understandable installation guide on how to actually install this pack.

After searching for even longer, finally found the CF Project page here it would be nice if that project would be more up to date with the repository and/or linked here at all
