# UNO reference

Each template in the UNO is designed to do one thing and do it brilliantly.

In contrast with Studio's playlist-centric operation environment, UNO template interfaces have optimal operation environments for single overlays (i.e. a soccer scorebug or countdown clock).

## User interface

### Output window

### Control panels

#### Customize

The customize panel allows you to customize pre-defined elements of an overlay's style. These properties vary with each overlay but frequently contain color and effects settings.

## 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://developer.singular.live/singular-basics/controlling-overlays-in-studio-and-uno/uno-reference.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.
