In Joomla!, you create content groups before you can actually start adding articles and menu links. Sections are the main, high-level way to organize your site; categories are the second level. When you add sections and categories in the backend you'll notice nothing changes on the frontend. Sections and categories aren't automatically shown on the site. To get them to display we'll create a menu link pointing to this section and category content later.

By defining a section and some categories you've now got a foundation to add any amount of content on these two main subjects. In later chapters, we'll expand this structure.

Now we come to the core of content management and actually start creating content! We'll make some articles, apply the appropriate formatting, and add images.
