How can I install something not rpm based to core silverblue

Does anyone know how to add something to silverblue base that is not rpm based? Supposing I needed a system monitoring tool, for example. Would this be a case of using ostree something like this:

ostree checkout latest-ref ~/dir
modify ~/dir
ostree commit …
ostree admin deploy

Has anyone tried this? With what degree of success?




Hello @tigerpaws
ostree is in packages.
But most software has a website with a manual for install, like this one for ostree
