Quick Deluge Installation
Use apt-get command,
sudo apt-get install deluge-torrent
You can start Deluge by visiting Application > Internet > Deluge Bittorrent Client
Change port settings
The official ports for BitTorrent are 6881-6889, but most ISPs block or at least throttle those ports, so I recommend to use a port range of something between 50000 and 65535 or any other random range. You can change port range from Preference > Select Network tab > Setup new range > Close
