 # AF_XDP Plugins for Kubernetes
 
 A Kubernetes device plugin and CNI plugin to provide AF_XDP networking to Kubernetes pods.
+
+## Deploy the Plugins
+Assuming you have a functional Kubernetes cluster and environment as described in the [prerequisites](#running-the-plugins), the plugins can be deployed with the following command: `kubectl apply -f https://github.com/intel/afxdp-plugins-for-kubernetes/main/deployments/daemonset.yml`
+
+This will deploy the daemonset with the default configuration described in [deployments/daemonset.yml](./deployments/daemonset.yml).
+Alternatively, to customize the configuration:
+- Download daemonset.yaml: `wget https://github.com/intel/afxdp-plugins-for-kubernetes/main/deployments/daemonset.yml`
+- Update daemonset.yml with the required configuration. See the [Device Plugin Config](#device-plugin-config) section.
+- Deploy the plugins with the updated config: `kubectl create -f daemonset.yml`
+
+## Running AF_XDP Pods
+
+- Create a network attachment definition file. This is the config for the CNI plugin.
+	- An example file can be found under [examples/network-attachment-definition.yaml](./examples/network-attachment-definition.yaml)
+	- Change the config if necessary. See comments in the example file.
+	- `kubectl create -f network-attachment-definition.yaml`
+- Create a pod spec:
+	- An example pod spec can be found under [examples/pod-spec.yaml](./examples/pod-spec.yaml)
+	- Configure the pod spec to use a suitable Docker image and to reference the network attachment definition as well as the resource type from the Device Plugin. See comments in the example file.
+	- `kubectl create -f pod-spec.yaml`
+

 ### Pool Drivers
 In production environments, the most common way to add devices to a pool is through configuring drivers for that pool. When a driver is configured to a pool, the device plugin will search the node for devices using this driver and add them to that pool. A pool can have multiple drivers associated with it. Drivers are identified by their name.
