How do I advise users to install the arch package for Cpdf?

Hello, Someone has kindly provided an Arch package for a piece of software I wrote: https://aur.archlinux.org/packages/cpdf I had thought it could be installed with pacman -S cpdf, and not being an arch user, that's what I'd put in the documentation. In fact, this is not true, because it's in the AUR. I installed Arch, and yay, and ran: yay -S cpdf which completed successfully. But running 'cpdf' at the command line cannot find the command. And yet, from the comments, other people are using it successfully. Any advice on what I can tell my users? Or a better venue to ask this question?
