+# Most development Docker images are built and run as root. That doesn't work
+# here because the `bower` command run within the `make` step, refuses to run as
+# root.
+#
+# To build this Docker image, run:
+#
+# docker build -t mediagoblin-python3 -f Dockerfile-python3 # or
+# docker build -t mediagoblin-python3 - < Dockerfile-python3 # with no build context
+#
+# The "- < Dockerfile" format advises Docker not to include the current
+# directory as build context.
+#
+# Before running the image you first need to first assign the "mediagoblin" and
+# "user_dev" directories to an artificial group (1024) on the host that is
+# mirrored within the image (details below):
+#
+# sudo chown --recursive :1024 mediagoblin user_dev
+# find mediagoblin user_dev -type d -exec chmod 775 {} \;
+# find mediagoblin user_dev -type f -exec chmod 664 {} \;
+#
+# Then you can run the image with the upstream MediaGoblin code:
+#
+# docker run --interactive --tty --publish 6543:6543 mediagoblin-python
+#
+# Or you can run with your local "mediagoblin" and "user_dev" directories
+# bind-mounted into the container. This provides automatic code reloading and
+# persistence:
+#
+# docker run --interactive --tty --publish 6543:6543 --volume ./mediagoblin:/opt/mediagoblin/mediagoblin --volume ./extlib:/opt/mediagoblin/extlib mediagoblin-python3
+#
+# Alternatively you use docker-compose instead of separate build/run steps:
+#
+# sudo chown --recursive :1024 mediagoblin user_dev
+# find mediagoblin user_dev -type d -exec chmod 775 {} \;
+# find mediagoblin user_dev -type f -exec chmod 664 {} \;
+# docker-compose up --build
