Do we have a Lemmygrad introductory "course" to Marxism? Should we build one?

AFAIK, we you join pretty much any communist party they give you materials for basic comprehention and provide you with some materials. It generally is some extract of a text and some party written stuff, maybe we could do something like that. Or a very brief and short text, and a "bigger" one for a bit more in depth understanding (complete Communist Manifesto and a few more articles/short book)?
