# Scan Document

> Scan Document Animation

A AI Orb component for React, Tailwind and shadcn by @iurvish, version 1.0.0, MIT licence.

Click Scan and a page unfolds, flips, and a glowing bar reads it. Done holds, then it resets.

## Install

```bash
npx layro-cli add @iurvish/scan-document
```

Or with shadcn: `npx shadcn@latest add https://layro.dev/r/iurvish/scan-document.json`

npm packages: motion
