     <string name="question_19">What is torrent? How do I use it?</string>
     <string name="answer_19">Torrent or formally known as BitTorrent is an internet communication protocol for peer\-to\-peer file sharing. A torrent network doesn\'t use a centralised server to host files. It shares files in a decentralised manner. A torrent network has two types of peers. Seeders &amp; Leachers.\n\n• Seeders : These are peers who completed downloading and has the full file. And now they are sharing this file to other peers which is called seeding. A torrent cannot work without at least one seeder. The more seeder a torrent has, the better.\n\n• Leachers : These are peers who are currently downloading the file. If they currently have 40&#37; downloaded then they will share the 40&#37; to any other peers who requests it.\n\nUnlike a centralised server, torrents have no bandwidth limit. You can get your files from hundreds of seeders at the highest possible speed your internet can offer. But many ISP throttle torrent to slow them down because it\'s demanding on their infrastructure. Use a VPN to circumvent this.\n\n• How to use torrents :\n\n1. Install the Torrent Add-on from \`Dantotsu &gt; Settings &gt; Add-ons &gt; Torrent Add-on.\` \n2. Get a source that provides torrents.\n3. USE A VPN. Using VPN while torrenting only has upsides. Without a VPN your IP address will be exposed, your ISP will throttle your network and you could possibly be fined if you live in a country first world country. DO NOT USE IT WITHOUT A VPN IF YOU DON\'T KNOW WHAT YOU\'RE DOING.\n4. Now use that source to start torrenting.</string>
