Zero to Hero: A comprehensive course to building an Alexa Skill

Support code for "Zero to Hero: A comprehensive course to building an Alexa Skill", an ASK training course in multiple languages. This is progressive code that starts from scratch and adds features on each module. The Learn more links below are suitable for learning (and teaching) how to code Alexa skills (see the README file on each module for video links and instructions on how to evolve the code departing from the previous module).
