command_to_start (e.g. rackup or rails s) Navigate to http://localhost:4567/

Later on, you can add screenshots and additional information to your heart's content, but make sure you have this with all your repos as you proceed through the course. You will thank yourself later. https://github.com/matiassingers/awesome-readme
