+`bash <(curl -L http://git.chrissexton.org/cws/dotfiles/raw/master/setup.sh) -n "<<YOUR NAME>>" -e "<<YOUR EMAIL>>" -i`
 
 You may customize the irssi configuration with the `server`, `port`, `nick`, and `password` options. Any of these options may be specified by environment variables instead of switches.
