Working with Alexa: Build a Flashcard SkillGo to Lab
It's a good lab. Minor issues with UI changes since it was written. However as part of the Alexa Developer quest it is striking that the steps are identical to at least 3 other Alexa Skills labs. Each one should ideally teach about the differences between the types of skills ( ie the code) not just repeat the same UI steps using a different upload sample code file each time.
