+## How to use
+
+Make sure to swap out the IP addresses in the ***deez_nodes*** file if they changed.
+Then simply use the following command:
+
+```
+ansible-playbook -i deez_nodes h1.yml h2.yml r1.yml
+```
+
+You might need to have the hosts inside of your know_hosts file in .ssh in order for this to work.
