-And be sure to push your images to a public registry (or load them locally to your development cluster).
+Note that these are available under the flux-framework organization GitHub packages, so you shouldn't need

+If you do build (and use a different name) be sure to push your images to a public registry (or load them locally to your development cluster).
 Remember that if you just want to test locally, you can jump to the [local usage](#local-usage) section.
