-## Instructions
-
-Bring up a Debian Jesse instance using Vagrant, or, use the provisioning script
-on a Debian Jesse server of your own. When it is done running, all necessary
-package build requirements for either `apt`-based or `rpm`-based distros will
-be present. See the [`README.md`](README.md#tldr) document for instructions on
-building packages.
+See [`rabbitmq/build-env-images`](https://github.com/rabbitmq/build-env-images) and [`rabbitmq/server-packages`](https://github.com/rabbitmq/server-packages?tab=readme-ov-file).
