+# Azure CLI AppnetPreview Extension #
+This is an extension to Azure CLI to manage Application Network resources.
+
+## How to use ##
+
+### Install the extension
+```bash
+az extension add --name appnet-preview
+```
+
+### List available Application Network versions
+```bash
+az appnet list-versions --location <location>
+```
+
+### Create an Application Network
+```bash
+az appnet create --resource-group <resource-group> --appnet-name <name> --location <location>
+```
+
+### Join an AKS cluster to an Application Network
+
+**Prerequisites:** You must have an existing AKS cluster before running `az appnet member join`.
+
+```bash
+# Create an AKS cluster first (if you don't have one)
+az aks create --resource-group <resource-group> --name <aks-name> --location <location>
+
+# Get the AKS cluster resource ID
+AKS_ID=$(az aks show --resource-group <resource-group> --name <aks-name> --query id -o tsv)
+
+# Join the AKS cluster to the Application Network
+az appnet member join --resource-group <resource-group> --appnet-name <appnet-name> \
+    --member-name <member-name> --cluster-type AKS --member-resource-id $AKS_ID \
+    --upgrade-mode FullyManaged --release-channel Stable
+```
+
+### Other commands
+```bash
+# List Application Networks
+az appnet list --resource-group <resource-group>
+
+# Show an Application Network
+az appnet show --resource-group <resource-group> --name <appnet-name>
+
+# List members in an Application Network
+az appnet member list --resource-group <resource-group> --appnet-name <appnet-name>
+
+# Remove a member from an Application Network
+az appnet member remove --resource-group <resource-group> --appnet-name <appnet-name> --member-name <member-name>
+
+# Delete an Application Network
+az appnet delete --resource-group <resource-group> --name <appnet-name>
+```
