-## 1. BUILD ARGS
-# These allow changing the produced image by passing different build args to adjust
-# the source from which your image is built.
-# Build args can be provided on the commandline when building locally with:
-#   podman build -f Containerfile --build-arg FEDORA_VERSION=40 -t local-image
-
-# SOURCE_IMAGE arg can be anything from ublue upstream which matches your desired version:
-# See list here: https://github.com/orgs/ublue-os/packages?repo_name=main
-# - "silverblue"
-# - "kinoite"
-# - "sericea"
-# - "onyx"
-# - "lazurite"
-# - "vauxite"
-# - "base"
-#
-#  "aurora", "bazzite", "bluefin" or "ucore" may also be used but have different suffixes.
-ARG SOURCE_IMAGE="silverblue"
-
-## SOURCE_SUFFIX arg should include a hyphen and the appropriate suffix name
-# These examples all work for silverblue/kinoite/sericea/onyx/lazurite/vauxite/base
-# - "-main"
-# - "-nvidia"
-# - "-asus"
-# - "-asus-nvidia"
-# - "-surface"

-# - stable
-# - stable-nvidia
-# - stable-zfs
-# - stable-nvidia-zfs
-# - (and the above with testing rather than stable)

-## this is a standard Containerfile FROM using the build ARGs above to select the right upstream image

 # Purpose
 
-This repository is meant to be a template for building your own custom Universal Blue image. This template is the recommended way to make customizations to any image published by the Universal Blue Project:
-- [Aurora](https://getaurora.dev/)
-- [Bazzite](https://bazzite.gg/)
-- [Bluefin](https://projectbluefin.io/)
-- [uCore](https://projectucore.io/)
-- [main](https://github.com/ublue-os/main/)
-- [hwe](https://github.com/ublue-os/hwe/) 
-
-This template includes a Containerfile and a Github workflow for building the container image. As soon as the workflow is enabled in your repository, it will build the container image and push it to the Github Container Registry.

 ## Containerfile
 
-This file defines the operations used to customize the selected image. It contains examples of possible modifications, including how to:
-- change the upstream from which the custom image is derived
-- add additional RPM packages
-- add binaries as a layer from other images
+The top line is the base image you want to start FROM. Any valid image can be a starting point, examples include:
+
+`FROM ghcr.io/ublue-os/bazzite:latest`
+`FROM ghcr.io/ublue-os/bluefin:stable`
+`FROM ghcr.io/ublue-os/aurora-dx:stable`
+
+## "Emtpy base images"
+
+These contain a base system WITHOUT a prexisting desktop. This is recommended for 
+
+`FROM ghcr.io/ublue-os/base-main:latest`
+
+Use `base-nvidia:latest` if you need the Nvidia drivers. You can also lock to a specific version like `base-nvidia:41`, etc.
