+Docker base image with [Chaperone](https://github.com/garywiz/chaperone),
+a minimal init daemon for container images.
+
+Users of this base image should provide their own chaperone configuration
+files and install them in */etc/chaperone.d*, as well as setting the
+Docker ENTRY\_POINT to */usr/local/bin/chaperone*.
