Wiki > cross-seed
"Cross-seeding is the term used for downloading a torrent from one tracker and then using that data to seed across different trackers. Generally, this is not against the rules, but you should always check and abide by your trackers' rules.
Since you already have the torrent's files, this results in zero download and instant seeding. This is a great way to build ratio (especially on your new trackers) and contribute to the torrenting community."
Installation
yarn global add node-gyp cross-seed
echo "PATH=\$HOME/.yarn/bin:\$PATH" >> ~/.bashrc && source ~/.bashrc
Generate a configuration with cross-seed gen-config
