Learnery is a rails engine you can use in your rails app to organize open learning events, like railsbridge, barcamps, user groups, meetups, hackathons.
You can easily deploy the app to heroku in a few simple steps.
Look at the URL of this site: http://learnery-staging-webdev.herokuapp.com/ is the official demo site of learnery-webdev (this app) using the learnery-engine.
Do you see a differnt URL? Then this is some other installation based on the same code, showing the default static pages that come with it.
