## What it is
A set of React components for annotating PDF documents, built on top of PDF.js. It supports text and image highlights, popover text for highlights, and scrolling to highlights.

## Use cases
- add text highlights to pdfs in a react app
- annotate pdf documents in the browser
- build a pdf viewer with highlighting
- display popovers on pdf highlights
- scroll to specific highlights in a pdf
- let users highlight text in uploaded pdfs

## When to choose
- you need interactive PDF annotation in a React application
- you want text and image highlighting on top of PDF.js rendering
- you need programmatic scroll-to-highlight behavior

## When to avoid
- your project does not use React
- you need PDF generation or editing rather than annotation
- you need a full standalone PDF viewer outside a web app
