By putting all of your content into nested categories you can give users and search engines access to everything using a menu.
Below you can see a Site Map of the menu items in the menu above.
Placing the Site Map within this article has involved some additional Joomla experience. The SiteMap you see below has been achieved by creating A Site Map Module and loading that module into this article's content area.
There are two types, or forms, of SiteMap: Human Site Map, and Search Engine Site Map - below you can see the Human Site Map.
In Joomla version 3.10.x Modules are created and managed via the administrator area menu 'Extensions' tab.
