+		<p>
+			This is a torrent file, which means you will need a torrent client to
+			download it. Here are some good torrent clients for various platforms:
+		</p>
+		<ul>
+			<li><a href="https://transmissionbt.com/download">Transmission</a> (Linux, Mac, Windows)</li>
+			<li><a href="https://www.qbittorrent.org/download">qBittorrent</a> (Linux, Mac, Windows)</li>
+			<li><a href="https://play.google.com/store/apps/details?id=org.proninyaroslav.libretorrent">LibreTorrent</a> (Android)</li>
+		</ul>
+		<p>
+			After installing your torrent client you will be able to use the
+			<a href={magnet}><Magnet/> Open magnet link</a>
+			button to download the files in your torrent client.
+		</p>
+		<h3>What is a torrent?</h3>
+		<p>
+			<a href="https://wikipedia.org/wiki/BitTorrent">BitTorrent</a> is a
+			peer-to-peer network for sharing files. This torrent file does not
+			actually contain the files listed below, instead it contains
+			instructions for your torrent client to download the files from
+			other people who happen to be downloading the same files currently.
+			This means that instead of connecting to a single server (like
+			pixeldrain), you will be connecting to other people on the internet
+			to download these files.
+		</p>
+		<p>
+			Torrents are a highly efficient and free method of transferring
+			files over the internet. Since the bandwidth is shared directly
+			between users there is no need for expensive servers to host the
+			files for you.
+		</p>
+		<h3>Is this safe?</h3>
+		<p>
+			Your torrent client will make sure that the files you receive from
+			your peers are actually what they say it is. This makes it just as
+			safe as any other form of downloading. Like always when downloading
+			files you still need to be aware of what you are downloading. Don't
+			just blindly trust any file anyone sends you.
+		</p>
+		<h3>Is it private?</h3>
+		<p>
+			When downloading a torrent file you will be part of the so-called
+			'torrent swarm'. Anyone in the swarm can see each other's IP
+			addresses. This is not a bad thing on its own, but there a few cases
+			in which this can be abused.
+		</p>
+		<p>
+			Anyone in the swarm will be able to see what you are downloading,
+			even across different torrents. This is something to keep in mind
+			when downloading torrents. If someone can link your IP address to
+			your identity then there are ways to find out which files you have
+			downloaded in the past (provided that your IP address has not
+			changed since then).
+		</p>
+		<p>
+			If you are downloading copyrighted material (which I do not condone)
+			then rightsholders will be able to see your IP address. In most
+			cases this is not a problem because your ISP will still protect your
+			identity. But there are some countries (notably the USA) where your
+			ISP will not respect your right to privacy and the rightsholder will
+			be able to contact you. If this worries you then you should look
+			into VPN services to protect your privacy, like <a
+			href="https://mullvad.net">Mullvad</a>.
