Title: Interactive Guide enhancements and update of README

While going through the interactive guide ( really cool feature by the way), I found myself with the need to go back to a previous topic, so I added a "Previous" and a "Skip" button. Feel free to pull it if you like it !

I also updated the README file to add a Prerequisites section - I thought people new to NodeJS and interested in Supergrep might want to know they need to install Node.js and npm.
