Categories - How to add them to a page
Categories are made by adding
at the bottom of a page (for the category 'Timeline pages').
It doesn't matter where you put the category code in a page, but for cleanliness of your editing page, please put it at the bottom.
To add other categories, simply add a new line, for example
If you want to the category 'SMMA-HR' to be a subcategory of the category 'Biography pages' then simply add
to the page that was generated for the Category:SMMA-HR.
The software automatically generates pages with alphabetical lists of all subcategories and pages in a category.
