During rebase rpminspect.yaml and README.rst files were removed as they

+===================
+qemu-kvm development
+===================
+
+qemu-kvm is maintained in a `source tree`_ rather than directly in dist-git.
+This provides way to develope using regular source code structure and provides 
+way to generate SRPM and build using koji service. In addition, local build using
+CentOS 9 Stream specific configuration.
+
+Developers deliver all changes to source-git using merge request. Only maintainers
+will be pushing changes sent to source-git to dist-git.
+
+Each release in dist-git is tagged in the source repository so you can easily
+check out the source tree for a build. The tags are in the format
+name-version-release, but note release doesn't contain the dist tag since the
+source can be built in different build roots (Fedora, CentOS, etc.)
