+Testing
+-------
+
+There's a Vagrant_ configuration in the ``vagrant-test`` subdirectory
+that will turn up a test three-node cluster (with Debian) using
+pre-packaged binaries. To run it::
+
+    $ cd vagrant-test
+    $ vagrant up
+
+It will take a while to download the base image the first time, then
+it will turn up three nodes called **node1**, **node2** and **node3**.
+Use ``vagrant ssh`` to inspect them.
