+To (re)generate these test cases use the tool `./tools/gen-manifests`.
+The tool clones the [osbuild/images](https://github.com/osbuild/images)
+repository at the version specified in the `go.mod` file and runs the
+`cmd/gen-manifests` tool to generate the manifests with the default
+configurations.
 
+Manifest generation can be restricted to only some distributions,
+architectures, or image types using positional arguments:
+- distros: comma-separated list of distribution names to generate manifests for
+- arches: comma-separated list of architectures to generate manifests for
+- images: comma-separated list of image types to generate manifests for
+
+All three arguments support globs.  For example:
 ```
-go run ./cmd/gen-manifests
+./tools/gen-manifests `rhel-9.*` `*64*` `*rhui*`
 ```
-will generate all manifests using the default options.
