They way they are doing it is wrong, nonetheless the general idea is something i do anyway.

Documenting code style, how to work etc. makes a lot of sense for everyone and i normally have good documentation.

The problem? I know what i do, i don't write the docs for myself but for others or for my future me who might forgotten things. The good thing? Writing it for me, others and LLMs makes it a lot more helpful day to day.

Instead of explaining myself multiply times to AI OR a Junior / new Team Member, i write it down once.
