+# This is a minimal Fedora install designed to serve as a Docker base image.

+###  Hacking on this image ###
+# This kickstart is processed using Anaconda-in-ImageFactory (via Koji typically),
+# but you can run imagefactory locally too.
+#
+# To do so, testing local changes, first you'll need a TDL file.  I store one here:
+# https://git.fedorahosted.org/cgit/fedora-atomic.git/tree/fedora-atomic-rawhide.tdl
+#
+# Then, once you have imagefactory and imagefactory-plugins installed, run:
+#
+#   imagefactory --debug target_image --template /path/to/fedora-atomic-rawhide.tdl --parameter offline_icicle true --file-parameter install_script $(pwd)/fedora-docker-base.ks docker
