Adding pages to categories
Hello, I noticed you are attempting to add articles directly to a category. In Wikipedia, we do not add items to a category by editing the category page, we add them by linking to the category from the individual articles' pages.

Please see Help:Category and in particular pay close attention to the section Help:Category.

And please read FAQ/Categorization as it states what I'm saying in a nutshell.

Add the category to the article, NOT the other way around.

Thank you and have a great day.--DB1729 (talk) 22:59, 21 January 2021 (UTC)
