Project definition in IntelliJ IDEA can seem complex at first sight, but you will find that it is very flexible and well designed. In this chapter, you learned about the project concepts, such as modules, libraries, facets, and artifacts. We looked at project creation and the process of importing. From now on, you will be able to create, import, and tweak your project structure in the IDE easily.

In the next chapter, we will talk about the core of IntelliJ IDEA, that is, the editor, and start actual coding.
