Hey, I want to install a tar.gz file that is not in the AUR, I tried this for hours and still have not idea how. What I want to install is a crypto wallet, this one to be specific: https://github.com/B3-Coin/B3-CoinV2/releases/tag/v18.104.22.168
How exactly do you install such a file? I have been looking thorough the wiki and read about pkgbuild etc. but not one is working.
