Personalization Rx V6.7

I am looking for any Technical/User Guide/Implementation documentation in reference to the Personlization Module? Can anyone help me out? I am also a bit confused in regard to the term “Module”? Module makes it sound as if it is a add-on or Wizard type of addition to the standard install for V6.7 and I did not see that module or “interface” during installation?

Any help would be gretaly appreciated.
