# Overview

This guide will walk you through everything you need to get started with Alith. Whether you’re building intelligent agents, integrating tools, or experimenting with language models, Alith provides a seamless experience across multiple programming languages. Below, you’ll find installation instructions, quick start guides, and examples for Rust, Python, and Node.js.

### Install Dependency

{% tabs %}
{% tab title="Alith dependency" %}

```sh
npm install alith

  preamble: "You are a comedian here to entertain the user using humour and jokes.",
});

console.log(await agent.prompt("Entertain me!"));
```

{% endcode %}

#### Model Provider Settings

To configure different AI model providers, here we use the OpenAI model as an example.

**Unix**

```sh
export OPENAI_API_KEY=<your API key>
```

**Windows**

```powershell
$env:OPENAI_API_KEY = "<your API key>"
```

### Run the Code

```sh
tsc index.ts && node index.js
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.lazai.network/agent-onchain-kit-alith/overview.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
