-## 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="bluefin"
-
-## 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"
-# - "-surface-nvidia"
-#
-# aurora, bazzite and bluefin each have unique suffixes. Please check the specific image.
-# ucore has the following possible suffixes
-# - stable
-# - stable-nvidia
-# - stable-zfs
-# - stable-nvidia-zfs
-# - (and the above with testing rather than stable)
-ARG SOURCE_SUFFIX=""
-
-## SOURCE_TAG arg must be a version built for the specific image: eg, 39, 40, gts, latest
-ARG SOURCE_TAG="latest"

-### 2. SOURCE IMAGE
-## this is a standard Containerfile FROM using the build ARGs above to select the right upstream image
-FROM ghcr.io/ublue-os/${SOURCE_IMAGE}${SOURCE_SUFFIX}:${SOURCE_TAG}

-### 3. MODIFICATIONS
-## make modifications desired in your image and install packages by modifying the build.sh script
-## the following RUN directive does all the things required to run "build.sh" as recommended.
