 # Dapr Conversation
 
+In this quickstart, you'll send an input to a Large Language Model (LLM) using Dapr's Conversation API. This API is responsible for providing one consistent API entry point to talk to underlying LLM providers.
+
+Visit [this](https://v1-15.docs.dapr.io/developing-applications/building-blocks/conversation/conversation-overview/) link for more information about Dapr and the Conversation API.
+
+> **Note:** This example leverages HTTP `requests` only.  If you are looking for the example using the Dapr Client SDK (recommended) [click here](../sdk/).
+
+This quickstart includes one app:
+
+- `conversation.go`, responsible for sending and input to the underlying LLM and retrieving an output.
+
+## Run the app with the template file
+
+This section shows how to run the application using the [multi-app run template files](https://docs.dapr.io/developing-applications/local-development/multi-app-dapr-run/multi-app-overview/) with `dapr run -f .`.  
+
+This example uses the Default LLM Component provided by Dapr for testing purposes. Here are other [supported Conversation components](https://v1-15.docs.dapr.io/reference/components-reference/supported-conversation/).
+
+Open a new terminal window and run the multi app run template:
+
+<!-- STEP
+name: Run multi app run template
+expected_stdout_lines:
+  - '== APP - conversation == Input sent: What is dapr?'
+  - '== APP - conversation == Output response: What is dapr?'
+expected_stderr_lines:
+output_match_mode: substring
+match_order: none
+background: false
+sleep: 5
+timeout_seconds: 120
+-->
+
+```bash
+dapr run -f .
+```
+
+The terminal console output should look similar to this, where:
+
+- The app send an input `What is dapr?` to the `echo` LLM.
+- The LLM echoes `What is dapr?`.
+
+```text
+== APP - conversation == Input sent: What is dapr?
+== APP - conversation == Output response: What is dapr?
+```
+
+<!-- END_STEP -->
