Good : Arch User Repository (AUR) or only short AUR. ( https://wiki.archlinux.org/title/Arch_User_Repository ) Or example command : yay -S zpaqfranz-git (?)

Installation good : ( I use paru, but yay is more common. https://pkgstats.archlinux.de/compare/packages#packages=paru,yay )

$ export LC_ALL=C && paru -S zpaqfranz-git

Thank you, looks reasonably good to me (for being the very first attempt)

This part doesn't look good to me:

        writing 96 bytes into a region 
        of size 64 overflows the destination 

The context: I've inserted line breaks for readability:
