# Languages

Portal languages are the languages into which the customer can switch your portal. If the customer’s language setting is in a language that your portal does not support, the portal will open in the primary language.

On the Portals page, in the details of the selected portal and in the languages tab, you can double-click the primary language (English screenshot on the screenshot) and you can activate/deactivate other languages.

{% hint style="warning" %}
In the textbox after the language, the abbreviation used is used to create subdomains for links to your portal in that language. Links that are already published will no longer work when you change them.
{% 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 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://cs.help.siesta.cloud/en/main/portaly/jazyky.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.
