+# Docker packaging
+
+This directory has one subdirectory per packaging distribution.
+At minimum, each of these subdirectories should contain a
+README.$DISTRIBUTION explaining how to create the native
+docker package and how to install it.
+
+**Important:** the debian and ubuntu directories are here for
+reference only. Since we experienced many issues with Launchpad,
+we gave up on using it to have a Docker PPA (at least, for now!)
+and we are using a simpler process.
+See [/hack/release](../hack/release) for details.
