Where find the source of the documentation of Functions of StringObject

Hi,

I would like to help, and improve the documentation.
For exemple this one:

StringToCharArray

I can't find the doc, I have search into GitHub - arduino/reference-en: Editable source for the Arduino Reference
Where can I get it and submit some patches ?

This function add the final '\0' and triggers question like this Arduino switch with chars - Stack Overflow

Use strings (small s) (char array terminated with '\0') rather than Strings (capital S) in the limited memory of an Arduino.

I agree, my question is about improve the documentation, I prefer C to C++. But lot of people use String, and functions are not well documented.
I would like to submit some docs improvement, but no way to find the repository with this doc.

See this Post in another Thread (which I had trouble finding again).

Usual lack of transparency from the management, but seems to be moving in the right direction.
