How do you use this?

There are no instructions on how to add a URL and Email?

$renderer = new ImageRenderer(
      new RendererStyle(400),
      new SvgImageBackEnd()
    );
    $writer = new Writer($renderer);
    $qr =  $writer->writeString($this->phone);

I can write the phone number or the email or the URL but how can you combine all of these?

What you are asking for is irrelevant to the library. But you need a vCard for that.

I normally use some generator like this: https://www.qr-code-generator.com/solutions/vcard-qr-code/ and then scan the QR code to get the format. And then just do the same in my code.
