By default it will run the nc:finished task after your deploy or deploy:migrations. If this behavior doesn't suit you, you can hook nc:finished to any custom task by editing deploy.rb:
after `your:task`, `nc:finished`
Terminal.app is opened when the notification is clicked. To use an alternative terminal set :nc_terminal to the bundle identifier e.g. set :nc_terminal, 'com.googlecode.iterm2' for iTerm2.
