What is a category?
When you first approach Joomla, one of the most important things to understand is how the system itself is organized. In order to help you remember what to do, think of this acronym – C.A.M.
C – First, you need a Category.
A – then create your Article and assign it to the appropriate category
M– then create a Menu item linking to the article and enable the module
The first step toward adding new articles or building new navigation is to start with adding a category. The category allows us to organize our articles by similar content. Categories are used when building menus that display dynamic content, such as category blogs, featured blogs, or category lists.
