# TeXLive

[TeX Live](https://www.tug.org/texlive/) is a free software distribution published by the [TeX Users Group](https://www.tug.org/) annually. It provides the LaTeX packages, fonts, TeX engines, and numerous software tools required to support LaTeX-based typesetting on all standard operating systems.

TeX Live is an important component of Overleaf because our servers use it to compile your LaTeX code and generate the real-time PDF preview. It also provides Overleaf’s users with easy access to over 5,000 LaTeX packages contained in each TeX Live release.

You are not restricted to using the latest version of TeX Live to compile your projects because Overleaf’s servers provide access to previous TeX Live releases. Projects can easily be switched to use an earlier version of TeX Live — for example, due to issues with package compatibility.<br>

## 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://overleaf-pro.ayaka.space/texlive/texlive.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.
