Installing it is super simple, just toss this in your
gem 'sopablackout', :git => "firstname.lastname@example.org:jakemarsh/sopablackout.git"

routes.rb and mount the engine at a route, (obviously it probably makes sense to mount it to
"/" so your whole site is blacked out).
mount Sopablackout::Engine => "/"
