+# Testing Locally
+
+### Requirements
+
+- [Vagrant](https://developer.hashicorp.com/vagrant/docs/installation)
+- [VirtualBox](https://www.virtualbox.org/wiki/Downloads)
+
+## Get Started
+
+```shell
+vagrant up                  # This will take a while
+vagrant ssh                 # Get a shell, password=vagrant
+
+# inside control VM
+/vagrant/scripts/push-keys  # Push the control VM's ssh key to all nodes
+
+# run ansible
+ansible-playbook playbook.yml --inventory local_testing/hosts.yaml --user vagrant
+
+```
+
+Below are the IPs of the VMs on the VirtualBox network
+```yaml
+vms:
+- control: 192.168.56.1
+- hopper: 192.168.56.2
+- lovelace: 192.168.56.3
+- neumann: 192.168.56.4
+- richie: 192.168.56.5
+- turing: 192.168.56.6
+```
+
+
+# Fixes/Notes
+
+### There was an error when attempting to rsync a synced folder.
