# Boxcar Deployment Notifications for Ruby on Rails

# In your config/deploy.rb:

task :production do
	# You will have other / more stuff here.  You want to add this though:

  set :deploy_notifications,  %W[example@example.com example2@example.com]
end

# Add our task hooks - notify_boxcar.

after "deploy", "deploy:notify_boxcar", "deploy:cleanup"
after "deploy:migrations", "deploy:notify_boxcar", "deploy:cleanup"

# And the magic happens here!
