Install a torrent client. The BitTorrent protocol lets you exchange or distribute data over the Internet. There's no central server involved; data is downloaded from other users (seeders). You need a client application that will connect to the host and manage the download. There are multiple clients available for free online. Some of the more popular applications are: μTorrent Vuze qBittorrent BitTorrent Deluge
Find a torrent tracker website. There are a variety of websites that list torrents. Some are more reliable than others. There are two main types of torrent trackers: Public and private trackers. Some trackers specialize in a specific type of media (i.e. movies, games, anime, etc). Public trackers are available to anyone. These are the sites you will find when doing a web search for torrent trackers. Because of their public nature, many torrents on public trackers are tracked by copyright holders, so downloading them can result in action from your internet service provider. Torrents from these websites are also more likely to malware and viruses. Private trackers require invites. These sites are not accessible until another member has invited you. They often have requirements, such as sharing an equal amount of what you download. Private trackers are much less likely to result in cease-and-desist letters from copyright holders. According to Oppido, you should always get your torrent from a trusted source, i.e. a website or a person that you know you can trust.
