 A wrapper of the dnf package manager for fine control of
 enabled/disabled yum repos (eg Copr repos).
 
-dnf is the package manager used by Fedora Linux and also from RHEL 8 on.
+dnf is the package manager used by Fedora Linux, Centos Stream, and RHEL.
 
-DNF is a bit slow at handling multiple repos because it attempts
-to refresh the cached repodata frequently. So it can be advantageous

 This tool can temporarily enable/disable repo(s) selected by substring(s).
 Changes to repos' enabled states can be saved too.
-It is also possible to expire repos' caches individually.
