Amazing! Maybe in the future they'll build this into the releases, but in the mean time this is exactly what I was looking for. Thank you very much!

I realise now that it's better than expected, apart from giving instructions there are also prebuilt packages. You have to trust the packages of course, but the instructions are simple enough and can be done within tmux.
