+# Vagrant Consul Demo
+
+This demo provides a very simple Vagrantfile that creates two nodes,
+one at "172.20.20.10" and another at "172.20.20.11". Both are running
+a standard Ubuntu 12.04 distribution, and Consul is pre-installed.
+
+To get started, you can start the cluster by just doing:
+
+    $ vagrant up
+
+Once it is finished, you should be able to see the following:
+
+    $ vagrant status
+    Current machine states:
+    n1                        running (vmware_fusion)
+    n2                        running (vmware_fusion)
+
+At this point the two nodes are running and you can SSH in to play with them:
+
+    $ vagrant ssh n1
+    ...
+    $ vagrant ssh n2
+    ...
+
+To learn more about starting Consul, joining nodes and interacting with the agent,
+checkout the [getting started guide](http://www.consul.io/intro/getting-started/install.html).
