+# This Dockerfile is meant to be built on top of an existing image from the base-images directory.
+# Suggested usage, from the SDK root:
+#   docker build -t base/bullseye -f etc/docker/base-images/Dockerfile.debian.bullseye .
+#   docker build --build-arg BASE_TAG=base/bullseye --build-arg GIT_TAG=[...] etc/docker/Dockerfile.sdk-build .
+# You can substitute the bullseye image for whichever you want to use as a base.
+# Note that it is necessary to tag the base image with `-t` and then refer to it using the `BASE_TAG` arg.
