Under the header '8.1. Installing a JSF Implementation' and sub header 'Add the JSF Implementation JAR File' third point reads as follows:

Add a module.xml file in the same subdirectory, similar to the Mojarra or MyFaces template examples.

In source community documentation (https://docs.jboss.org/author/display/WFLY10/JSF+Configuration) there are hyperlinks to concrete examples, but there are none in product documentation.

Template examples are omitted in several places and without them, the instructions don't make sense. Please add the hyperlinks or templates itselves to the book.
