+## Prerequisites
+
+The application Ai Chat menu option requires an Azure Open AI subscription with "gpt-4o" model deployed.
+Please, create these secrets on the Kubernetes Namespace of your application deployment, like as showing here:
 
 ```bash
 kubectl create secret generic azure-openai-url --from-literal=AZURE_OPENAI_API_URL=<your Azure Open AI URL here> -n blazorintapp1
 
 kubectl create secret generic azure-openai-key --from-literal=AZURE_OPENAI_API_KEY=<your Azure Open AI Key here> -n blazorintapp1
 ```
+
+In development, you can use the dotnet secrets to store your App secrets.
+In Visual Studio, right-click the project in Solution Explorer, and select Manage User Secrets from the context menu.
+Add your secrets as showing here:
+```json
+{
+  "AzureOpenAIUrl": "<your Azure Open AI URL here>",
+  "AzureOpenAIKey": "<your Azure Open AI Key here>"
+}
+```
+
+## Running the app with a Load Balancer service
+

+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: blazorintapp1
+  namespace: blazorintapp1
+  labels:
+    kubernetes.azure.com/generator: devhub
