I can help with swedish translations.
Thanks! You can start by making a fork of https://github.com/rocky-linux/rocky.
Add a new file like README.sv_SV.md to your fork, and when it is ready you can make a pull request in the main repo.
Started helping out with the Swedish translation aswell 
Hi!
I just made a pull request for an updated version of the README in Swedish. if anyone wants, I’d be glad to have a discussion in order to bring the README to a good state.
Updated the Swedish translation for the website today
