1. First select a file using the file selector. Be weary that the current WebTorrent libary has issues with large files in browsers.
2. Click Add torrent, this will load the torrent into the indexedDB store, save the metadata, then destroy the torrent (wait for it).
3. Stay or reload the page and click resurrecting, this will load the torrents back into the WebTorrent client from the indexedDB store!
0. Don't forget to delete indexedDB store after you're done, programatically itterating through all indexedDB on a website is impossible currently!
I'm not an interface designer, sorry for the lack of styling!
