Site Help: What is a technology, playlist, course, and lesson?

Technologies are categories for organizing courses and lessons. Courses are a collection of lessons created to cover a topic cohesively. Playlists are also collections of lessons, but not necessarily as cohesive. Users can create playlist. Ever user has a "watch later" playlist to add lessons that they want to... watch later.

Only instructors can create courses!

We have lots of individual lessons that aren't in a course. <- check it out!
