+HTML example with status showing UI
+
+This complete HTML example mimics the UI of the webtorrent.io homepage. It downloads the sintel.torrent file, streams it in the browser and outputs some statistics to the user (peers, progress, remaining time, speed...).
+
+You can try it right now on CodePen to see what it looks like and play around with it!
+
+Feel free to replace torrentId with other torrent files, or magnet links, but keep in mind that the browser can only download torrents that are seeded by WebRTC peers (web peers). Use WebTorrent Desktop or Instant.io to seed torrents to the WebTorrent network.
