    <h3>Working with file-input</h3>
    <p>This example let's you select an image from your local filesystem.
        There is no server interaction needed as the file is
        simply accessed through the
        <a href="http://www.w3.org/TR/file-upload/">File API</a>.
    <p>This also works great on a wide range of mobile-phones where the
        camera access through <code>getUserMedia</code> is still very
        limited. </p>
    <p>If the default configuration does not suit your use-case, you can
        adjust various parameters of the localization and decoding process.</p>
