+## Quickstart
+
+### Basic Agent - Python
+
+Create a simple Azure Responses Agent that writes a haiku about the Microsoft Agent Framework
+
+```python
+import asyncio
+from agent_framework.azure import AzureOpenAIResponsesClient
+from azure.identity import AzureCliCredential
+
+async def main():
+  # Initialize a chat agent with basic instructions
+  agent = AzureOpenAIResponsesClient(credential=AzureCliCredential()).create_agent(
+    name="HaikuBot",
+    instructions="You are an upbeat assistant that writes beautifully.",
+  )
+
+  print(await agent.run("Write a haiku about Microsoft Agent Framework."))
+
+asyncio.run(main()) 
+```
+
+### Basic Agent - .NET
+
+```c#
+using System;
+using Azure.AI.OpenAI;
+using Azure.Identity;
+using Microsoft.Agents.AI;
+
+var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")!;
+var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME")!;
+
+var agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential())
+    .GetOpenAIResponseClient(deploymentName)
+    .CreateAIAgent(name: "HaikuBot", instructions: "You are an upbeat assistant that writes beautifully.");
+
+Console.WriteLine(await agent.RunAsync("Write a haiku about Microsoft Agent Framework."));
+```
