# Getting to know Chamilo

Chamilo LMS is an e-learning system (that is it manages learning) developed in a collaborative way by several companies, associations and people, through an open model called « free software » (as in *freedom*).

You can download and use Chamilo freely, given you accept its license (GNU/GPLv3) which gives you, in short, four essential freedoms, given your compromise to maintain those freedoms : the freedom to use, study, modify and distribute the software.

*Illustration: Right to use, study and modify, share and distribute the software*

Chamilo is not only developed collaboratively by dozens of people in the world at large ; it is also supported by a non-profit association with the objective of promoting the platform and ensure its continuity. In this sense, Chamilo LMS is the only free software e-learning platform that generates so many guarantees of open access.

You can contribute to Chamilo too, promoting its use, reporting errors, suggesting improvements, translating it (or its manuals) to your native language, or even developing extensions or fixes by yourself.

## 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://docs.chamilo.org/1.11.x/admin-guide/chamilo-_what_is_it.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.
