The Hugo documentation is really hard to understand for begginers. The name of the feature used are not easy to find see example here.
Access to knowledge in Hugo is limited or restricted my opinion as I mentioned here
Also there are things you cannot find the answer to in documentation like this one Select params.title 2 words separately - #5 by pitifi9191
after 3 months of trying and after getting my account blocked, I quit on the documentation improvement. So good luck and thanks for discussing this as it is really needed.
