+# Getting started with Network Policy API
+
+**1. Install a Network Policy API compatible CNI**
+
+There are numerous Container Network Plugin projects that support or are actively working on
+supporting the Network Policy API. Please refer to the [implementations](implementations.md)
+doc for details on the supportability matrix.
+
+**2. Install the Network Policy API CRDs**
+
+The following commands will install the latest release version of the `AdminNetworkPolicy` and
+`BaselineAdminNetworkPolicy` CRDs in your K8s cluster:
+
+```bash
+kubectl apply -f https://github.com/kubernetes-sigs/network-policy-api/releases/download/v0.1.0/install.yaml
+```
+
+**3. Try out one of the sample yamls for specific user stories**
