# Nodes

To build virtual agents on our platform you can utilize the boxes you see on the left side of the page. 

The boxes are called **nodes** and are the building blocks of the conversation. Each of them has its own purpose, and together they create the conversational flow. 

You can click on a box, drag it into the middle of the page, and can edit it accordingly by clicking on it again. It will open up on the right side of the page.

{% hint style="info" %}
*In order to create a flow, you have to connect the nodes to one another. Please connect them from the exit point of one module to the entry point of another.*
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://studio.docs.ai.vonage.com/voice/nodes.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
