 # TODO
 
-- Reduce image size of `jayfield/dosbox-novnc` (currently ~2.3GB).
+- ~~Reduce image size of `jayfield/dosbox-novnc` (currently ~2.3GB).~~ Done: merged the
+  game download/extract steps and the unzip/smbclient install into a single layer (so the
+  downloaded zips and the packages only needed to extract them no longer persist in the
+  final image). 2.31GB -> 1.6GB.
