 # containerfiles
-Containerfiles for Podman images
+
+These are Containerfiles I use with Podman on libostree-based Fedora distributions. Inspired by [jessfraz/dockerfiles](https://github.com/jessfraz/dockerfiles), but not nearly as bountiful, because these are intended to be used on an immutable ostree host where it is not feasible to run inside a toolbox container. I will eventually convert these to [podenv](https://github.com/podenv/podenv) configuration files, but, for want of more comprehensive documentation, it will take time to decode how Podenv configuration (and Podenv itself) works.
+
+Feel free to clone this repo and adapt these to your needs!
