Well, please excuse me for my ignorance! I’ve been away from Linux since 2013, 
and my first time on Arch.
I searched and found https://ostechnix.com/install-yaourt-arch-linux/
But it says:
**Important Update:**
Please don’t use Yaourt. It is out dated and discontinued. Use **Yay** AUR helper instead. https://ostechnix.com/yay-found-yet-another-reliable-aur-helper/
So, as far as my humble understanding, I better uninstall Yaourt as yay replaced it?
