# Welcome
## Introduction
Everything here is split into three sections: basics, assets and Figma.
**Basics**, as the name infers, is a lot of the design tokens and simple stuff that you should base all designs upon.
**Assets** is an excellent collection of each of the different types of asset we've prepared, which are great to use in content and publications.
**Figma** contains all of the links to our Figma documents, which are considered the ultimate source of truth.

## 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://design.cal.com/welcome.md?ask=&goal=
```
`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.
