+
+This how-to guide will provide an overview of how to:
+
+- Leverage a [Dapr sidecar](https://docs.dapr.io/concepts/dapr-services/sidecar/) with your Radius Application
+
+## Prerequisites
+
+- [Supported Kubernetes cluster]({{< ref "/guides/operations/kubernetes/overview#supported-kubernetes-clusters" >}})
+- [rad CLI]({{< ref getting-started >}})
+- [Dapr CLI](https://docs.dapr.io/getting-started/install-dapr-cli/)
+- [Radius initialized with `rad init`]({{< ref howto-environment >}})
+- [Dapr initialized with `dapr init -k`](https://docs.dapr.io/getting-started/install-dapr-selfhost/)
+
+## Step 1: Start with a container
+
+Begin by creating a file named `app.bicep` with a Radius [container]({{< ref "guides/author-apps/containers" >}}):
+
+{{< rad file="snippets/app.bicep" embed=true >}}
+
+## Step 2: Add a Dapr sidecar extension
+
+Now add the Dapr sidecar extension, which enabled Dapr and adds a Dapr sidecar:
+
+{{< rad file="snippets/app-sidecar.bicep" embed=true marker="//CONTAINER" >}}
+
+## Step 3: Deploy the app
+
+Deploy your application:
+
+```bash
+rad deploy ./app.bicep -a demo
+```
+
+Your console output should look similar to:
+
+```
+Building ./app.bicep...
+Deploying template './app.bicep' for application 'demo' and environment 'default' from workspace 'default'...
+Deployment In Progress... 
+...                  demo           Applications.Core/containers
+Deployment Complete
+Resources:
+   demo           Applications.Core/containers
+```
+
+## Step 4: Verify the Dapr sidecar
+
+Run `dapr list -k` to list all Dapr pods in your Kubernetes cluster:
+
+```bash
+dapr list -k
+```
+
+
+The console output should look similar to:
+
+```
+NAMESPACE      APP ID    APP PORT   AGE  CREATED              
+default-demo   demo      3000       29s  2023-11-30 21:52.59
+```
+
+## Done
+
+You've successfully deployed a Radius container with a Dapr sidecar! You can now interact with Dapr building blocks and the Dapr API from your container.
+
+
+## Cleanup
+
+Run the following command to [delete]({{< ref "guides/deploy-apps/howto-delete" >}}) your app and container:
+
+   ```bash
+   rad app delete -a demo
+   ```
