Above is a high level picture of what a Zydii course is and what it should accomplish, but Zydii courses are divided into modules and lectures and are made up of training presentations, video and audio files and documents.  For all of the specific criteria that makes up a Zydii course you’ll need the Zydii quality checklist. This is what the Zydii Review Team uses to evaluate your course after you publish.  You’ll need to hit all of the “Required” elements to be approved on the marketplace, and the “Recommended” items are key for making a good course great.
