+Debian Buster
+=============
+
+Stock Debian 10, installed via debootstrap from official debian image.
+
+This image also includes:
+
+* [gosu](https://github.com/tianon/gosu) to simplify sudo needs in dependant images.
+* [dumb-init](https://github.com/Yelp/dumb-init) to simplify signal handling.
+* `apt-install` a small wrapper for apt-get install, which cleans up caches after running.
