In this lesson we have discussed

Discussed the goals of the Modular JDK (as stated by Project Jigsaw)
Introduced you to standard and non-standard modules
Introduced you to a module graph and showed you the Java SE Module Graph
Introduced you to some of the options that Java and jdeps tools support for examining modules.

How to create a module and run it.
