Documentation For Personalizations - ADF Artifacts, Javascript, Expression Language

Summary

Is there a good documentation source for HCM personalizations that discusses ADF artifacts, JavaScript, and Expression language.

Content

There are many Youtube videos, Webexes, and so on that discuss different types of personalizations. Typically these are oriented towards a specific personalization such as hiding the phone number, making a field mandatory, and so on. And they are all very much appreciated. 

However, when I go to perform a personalization and use the "Source" option I see all kinds of components like panelGroupLayout, tableLayout, spacers, popups, and so on.

Is there a documentation source that explains what each of these are and how they all relate to each other?
