Download uTorrent 2.2.1 (no higher versions, they're sketchy as fuck) or any other good torrent program.
Get a VPN that allows P2P connections (I use NordVPN).
Go on the torrent site you prefer (KAT and IPTorrents are my favourite ones).
Find what you want to torrent, click the magnet link and begin torrenting.
Seed the torrent to at least 1:1 or gtfo.
Now you've torrented, congratulations.
