I'm pretty familiar with TTech's legacy, I just mention it because if the repos ever got compromised, it could be a shitshow. IDK what security measures the new maintainers use to secure their access or check PRs, but I get nervous when it's as popular as it is and such a good vector for complicated installations that are hard to check out. I also don't know the new maintainers from Adam.

Personally, I'd use the scripts as a guide for DIY.
