+<h3>Demo Project</h3>
+
+In `example/`, there are files to configure and deploy a demo project that, once your request is received, returns the IP of the cluster serving your request to demonstrate the use of Packet's Global IPv4 addresses to distribute traffic globally to your edge cluster deployments.
+
+To run the project, you can run the `deploy_demo` Ansible project by running the `create_inventory.sh` script to gather your cluster controller IPs into your inventory for Ansible:
+
+```
+cd example/
+sh create_inventory.sh
+cd deploy_demo
+ansible-playbook -i inventory.yaml main.yml
+```
+
+or manually copy `example/deploy_demo/roles/demo/files/traefik.sh` to your `kubectl` client machine and run manually to deploy Traefik and the application.

 The `trafik.sh` script will deploy the application as a DaemonSet on your cluster, and expose this through an ingress on port 80, by default, so from there, you can access the application (and verify the distribution of requests through the Anycast IP) using:
