[NTG-context] Re: (ConTeXt LMTX) (Beginner) how do i set up vertical CJK?

Where does one find this "followingup-directions.tex"? The only thing I am aware of existing is the ConTeXt wiki. It is very hard to navigate through this language's resources for me, perhaps that is due to this being the 'first' language I am truly trying to learn without the help of AI like I did with LaTeX. searching for followingup-directions.tex in context wiki shows nothing.
