+# While it is possible to copy the source from the current directory like this:
+#
+# COPY --chown=www-data:www-data . /opt/mediagoblin
+#
+# that approach to lots of confusing problems when your working directory has
+# changed from the default - say you've enabled some plugins or switched
+# database type. So instead we're doing a git clone. We could potentially use
+# `git archive` but this still wouldn't account for the submodules.
+#
+# TODO: Figure out a docker-only way to do the build and run from our local
+# version, so that local changes are immediately available to the running
+# container. Not as easy as it sounds. We have this working with docker-compose,
+# but still uses upstream MediaGoblin for the build.
