-# Example Setup and Testing
-
-In this `./example` folder, OVN4NFV-plugin daemonset yaml file, VLAN and direct Provider networking testing scenarios and required sample
-configuration file.
-
-# Quick start
-
-## Creating sandbox environment
-
-Create 2 VMs in your setup. The recommended way of creating the sandbox is through KUD. Please follow the all-in-one setup in KUD. This
-will create two VMs and provide the required sandbox.
-
-## VLAN Tagging Provider network testing
-
-The following setup have 2 VMs with one VM having Kubernetes setup with OVN4NFVk8s plugin and another VM act as provider networking to do
-testing.
-
-Run the following yaml file to test teh vlan tagging provider networking. User required to change the `providerInterfaceName` and
-`nodeLabelList` in the `ovn4nfv_vlan_pn.yml`
-
-```
-kubectl apply -f ovn4nfv_vlan_pn.yml
-```
-This create Vlan tagging interface eth0.100 in VM1 and two pods for the deployment `pnw-original-vlan-1` and `pnw-original-vlan-2` in VM.
-Test the interface details and inter network communication between `net0` interfaces
-```
