Documentation on installing rpmfusion

I give up, where is the documentation on installing rpmfusion free & nonfree codecs?
These instructions do not seem to work: https://rpmfusion.org/Configuration#Graphical_Setup_via_Firefox_web_browser
Neither the word codecs nor rpmfusion exist on wiki.almalinux.org
Trying to install a KDE (only) Desktop using AlmaLinux 9.2

Did you try this article?

What did you do and what was the perceived error?
