I am also a noobie 👊 but was able to get it running with a few commands.
I started here: https://github.com/grunch/rana
Then I installed rust using the command here:
https://www.rust-lang.org/tools/install
I then ran the following command as told at the rana github:
cargo install rana
From there I was able to run rana in the terminal. It went pretty smooth and I might have got lucky. Haha
