Add a “guide” / “manual” which explicitly demonstrates how to achieve autoloading of ROOT classes

[couet]

This question comes from: https://root-forum.cern.ch/t/acessing-custom-class-branches-in-python/46116/11

Is there any “guide” / “manual” which explicitly demonstrates how to achieve autoloading of ROOT classes (i.e., all steps needed without using CMake) ?

I'm not sure that this relates to this topic; I've noticed that the manual for "Adding a class" is missing (I couldn't find it) in the new ROOT Manual.

I'm trying to create a dictionary for my class, so the link you provided above is also helpful, it would be great to officially describe this process in the documentation!
