# Overview

References is where you look things up. Build and Consume tell you *how to do* a task; References holds *what to look up*: the full per-engine manuals, the complete syntax for every DataOS resource, and the interface specifications. Each fact lives here once, and the task sections link in for depth.

Use References when a task page sends you here for the full detail, or when you already know what you need and want the reference directly.

## What is here

If you are new to building or consuming, start in [Build](https://github.com/moderndatacompany/dataos/tree/july-7/documentation/build/README.md) or [Consume](https://github.com/moderndatacompany/dataos/tree/july-7/documentation/consume/README.md); they bring you here when you need the underlying detail.

# 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 dynamically by asking a question.

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

```
GET https://v2.dataos.info/references/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
