I'd like to see this image updated to be AlmaLinux-specific. If that's outside your wheelhouse, let me know! I can create one for you.

It would be great if you could create one, I tried creating something prior to this PR but it was horrible 😆.


The chart above illustrates the relationship between Fedora, CentOS Stream, and RHEL.<br>
AlmaLinux utilizes package sources from both RHEL and CentOS Stream to build its distribution. In contrast, Oracle Linux and Rocky Linux rely exclusively on package sources from RHEL.
