-## Libraries-7
-
-This module contains articles about various Java libraries. 
-These are small libraries that are relatively easy to use and do not require any separate module of their own.
-
-The code examples related to different libraries are each in their own module.
-
-Remember, for advanced libraries like [Jackson](/jackson) and [JUnit](/testing-modules) we already have separate modules. Please make sure to have a look at the existing modules in such cases.
