 Now that you have the testing infrastructure set up and all the necessary
 RPMs built, you can prepare a kickstart template for your new distro. You'll
 need to do [something like this](https://gitlab.cern.ch/linuxsupport/koji-image-build/-/commit/622b3632d9f1e6e89705e77694246cbfc5b2c068).
 
+## Upload the AIMS images

+You could have done this earlier, but now's as good a time as any. You have to
+upload an `vmlinuz` and `initrd.img` of your new distro to AIMS2:
