This is an official JetBrains MPS course, which represents an introduction into the topic of MPS coderules - the new way to define the type-system for custom languages in MPS. The course introduces the principles of coderules, explains the underlying mechanisms, demonstrates the capabilities and the syntax of the languages and leads you through a series of hands-on exercises.

After completing the course you will be able to define coderules for non-trivial DSLs. You will also have received useful directions to more advanced coderules topics.
