+# Puppet Tests
+Puppet Tests (or pup-tests) is a small project where I am learning Puppet by
+writing it. Some of this code was written while performing my duties as an
+employee of the University of Georgia.
+

+
+## Getting Started
+Puppet Tests is developed using the following technologies:
+* Vagrant 2.2.2 + vagrant-libvirt 0.0.45
+* Ansible 2.7.5
+* Puppet 4.8.2
+
+After installing the above, simply navigate to the root directory and deploy
+the virtual machines:
+
+`vagrant up`
+
+Vagrant will create at least two virtual machines and provision a puppet
+client-server architecture using Ansible code from the /setup/ folder. You will
+want to login to client:
+
+`vagrant ssh webserv`
+
+After logging into the puppet client, provision the machine:
+
+`sudo puppet agent -t`
+
