Introduction

• This script lets you set up and use a temporary DigitalOcean droplet to download torrent files.
• Once downloaded, they can be streamed down to your local machine.
• This uses transmission-cli for the torrent client, and nginx to serve files.

Create a droplet on DigitalOcean

• This assumes that you have a DigitalOcean account, have created a droplet, and seedbox-setup.sh is present in the current directory.
