This is the sample application for Michael Hartl's Ruby On Rails tutorial, from his "Learn Enough To Be Dangerous" series.

To get started with the app, clone the repo and then install the necessary gems:
$ bundle install --without-production
Next, migrate the database:
$ rails db:migrate
Finally, run the test suite to verify that everything is working correctly:
$ rails test
If the test suite passes, you'll be ready to run the app in a local server:
$ rails server
