Firstly, following the [installation guide](./website/articles/Installation.md) to install AutoGen packages.

Then you can start with the following code snippet to create a conversable agent and chat with it.

```csharp
using AutoGen;
using AutoGen.OpenAI;

var openAIKey = Environment.GetEnvironmentVariable("OPENAI_API_KEY") ?? throw new Exception("Please set OPENAI_API_KEY environment variable.");
var gpt35Config = new OpenAIConfig(openAIKey, "gpt-3.5-turbo");

var assistantAgent = new AssistantAgent(
    name: "assistant",
    systemMessage: "You are an assistant that help user to do some tasks.",
    llmConfig: new ConversableAgentConfig
    {
        Temperature = 0,
        ConfigList = [gpt35Config],
    })
    .RegisterPrintMessage(); // register a hook to print message nicely to console

// set human input mode to ALWAYS so that user always provide input
var userProxyAgent = new UserProxyAgent(
    name: "user",
    humanInputMode: ConversableAgent.HumanInputMode.ALWAYS)
    .RegisterPrintMessage();

// start the conversation
await userProxyAgent.InitiateChatAsync(
    receiver: assistantAgent,
    message: "Hey assistant, please do me a favor.",
    maxRound: 10);
```
