<p>This is a test page for the <a href="https://github.com/WICG/web-share">Web
Share API</a>. It will only work in browsers that have implemented the draft
proposal. At the time of writing, this works with:</p>
<ul>
<li>Google Chrome for Android 61 or higher (older versions can enable
chrome://flags#enable-experimental-web-platform-features).</li>
<li>Google Chrome for Chrome OS, Windows, or Linux, with
chrome://flags#enable-experimental-web-platform-features enabled, in
conjunction with a supported
<a href="https://github.com/WICG/web-share-target">web share target</a>
(<a href="https://wicg.github.io/web-share-target/demos/sharetarget.html">demo app</a>).</li>
</ul>
