To generate new schedule data, remove any generated HTML rows from the shuttle_schedule.rb, after the HTML comment. Make sure the gems are available:

bundle

From the project directory:

chmod +x generate.rb
bundle exec ruby generate.rb

Verify that new HTML data rows have been appended to shuttle_schedule.rb, based on the data file, shuttle_schedule_data.csv.

rackup

Navigate to http://localhost:9292 and verify the output rows.
