# Instructure UI

Instructure UI (or **InstUI**) is the React component library and design system that powers Instructure's products, including Canvas LMS. It contains 100+ packages (one per component, plus theme, icon, and utility packages) and is published under the `@instructure/*` scope on npm. For most consumers, the easiest way to get started is to add the [`@instructure/ui`](https://instructure.design/#usage) meta-package, wrap your app in the settings provider, and start rendering components. There are no global stylesheets to import and no CSS classes to memorize: styling is handled internally with [Emotion](https://emotion.sh/), and every component is themeable through the same provider.

We aim to make InstUI easy to use, easy to learn, and free from bloat. For this reason every component is built on a few shared principles. All components target [WCAG 2.1 AA](https://instructure.design/#accessibility) (and AAA when paired with the [canvas-high-contrast](https://instructure.design/#canvas-high-contrast) theme), support RTL languages, work with VoiceOver, NVDA and JAWS, and never hardcode user-facing strings, so every label is localizable.

Out of the box InstUI ships with 4 themes. Theming is scoped: you can swap themes for an entire app, or for a subtree, by nesting another settings provider. For teams using AI coding agents, the whole component library is also available as a single downloadable archive of markdown at [instructure.design/markdowns/documentation.zip](https://instructure.design/markdowns/documentation.zip), with an `llms.txt` catalog at [instructure.design/llms.txt](https://instructure.design/llms.txt). For everyone else, the rendered docs at [instructure.design](https://instructure.design) are the best place to start.

## 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://developerdocs.instructure.com/services/instui.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.
