To find the companies you're interested in, you can:

Simply click the rows of the companies you want to include in your Universe. They will become highlighted.
{% endstep %}

#### Add the selected companies to a universe
With your companies selected, click on the **Add XX to Universe** button (where XX is the number of companies you've selected). This action will reveal a list of your existing universes. You can then simply add the companies selected to a given Universe by simply clicking on its name.

## 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.tracenable.com/platform/company-universes-101/add-remove-companies-to-from-a-universe.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.
