Are there any CMS for documenting development and writing examples?

Question

PHP

Greetings!
The project is growing, doxygen used to manage, and others, but all the docks have to be written directly in the code, which personally infuriates me very much, namely, the description of the example of using the function is larger than the function itself, you must not forget to update the description of the parameters of functions and classes in a timely manner, everything is on your own to generate.
Ideally, as I see it:
In the code for each class / function, in addition to the standard description of the parameters, a certain identifier is added
; all code is loaded into this "CMS", respectively, as usual, pages for this class are automatically generated with all the functions, but with the possibility of simple editing and adding examples, descriptions, explanations.
In general, the main Wishlist is to bring maximum documentation and examples from the code to the site with the ability to easily edit everything and everything and not highly specialized, but where you can set the parsing of files according to templates, since development is carried out in several languages ​​and I want to see everything in one place.
