 Salt Sandbox is a multi-VM Vagrant-based Salt development environment used
 for creating and testing new Salt state modules outside of your production
 environment. It's also a great way to learn firsthand about Salt and its
 remote execution capabilities.
 
-Salt Sandbox will set up three separate virtual machines:
+https://github.com/elasticdog/salt-sandbox
 
-- salt.example.com - the Salt master server
-- minion1.example.com - the first Salt minion machine
-- minion2.example.com - the second Salt minion machine
+Salt Vagrant Demo
+=================
+A Salt Demo using Vagrant.

+https://github.com/UtahDave/salt-vagrant-demo
 
-These VMs can be used in conjunction to segregate and test your modules based
-on node groups, top file environments, grain values, etc. You can even test
-modules on different Linux distributions or release versions to better match
-your production infrastructure.
