This is a fairly basic rails application. It is written using Rails 5.0 and Ruby 2.2.2
To get started, create a new postgresql database and update the sample database.yml. note that the sample is not a postgres yml and you'll have to change that
To get started just pull down the application and run
bundle exec rake db:migrate
bundle exec rails s
And you should be good to go with a blank database at localhost:3000
