### Quick CDN usage

> **Important Note on HTTPS**: When using this library via CDN on HTTPS websites, always ensure you use the HTTPS version of the CDN URL to avoid mixed content errors.

```html
<!-- ✅ Correct: HTTPS URL -->
<script src="https://unpkg.com/html5-qrcode" type="text/javascript"></script>

<!-- ❌ Incorrect: HTTP URL (will cause mixed content errors on HTTPS sites) -->
<script src="http://unpkg.com/html5-qrcode" type="text/javascript"></script>
```

If you encounter a "Mixed Content" error, ensure you're using `https://` instead of `http://` in your script tag.
