 These set of repositories (or "compose") is for {{ fullname }} and was generated
 using Empanadas {{ version }} from the SIG/Core Toolkit.
 
-As this is not a traditional compose, there will be things that you might be
-expecting and do not see, or not expecting and do see. While we attempted to

+attempted to recreate a lot of those elements, it's not perfect and we don't
+expect that it ever will be. With that being said, in the future, we do plan on

+metadata provides.

 CHECKSUM Validation: https://github.com/rocky-linux/checksums
+                     https://git.resf.org/rocky-linux/checksums (mirror)
 
 Traditionally, we would "sign" the checksum files with the current GPG key of a
 major release. However, due to how the new build system operates and for
-ensuring strong security within the build system as it pertains the signing
-keys, this is no longer possible. It was determined by SIG/Core or Release
-Engineering to instead provide verified signed commits using our keys with
-RESF/Rocky Linux email domain names to a proper git repository. Our signing keys
-are attached to our GitHub and RESF Git Service profiles.

 If you are looking for "verification" of the ISO checksums and were expecting a
 `CHECKSUM.sig`, it is highly recommended to visit the link above instead.
