How to create a website with Joomla
Add new menu item:
The menus have the role of a navigation system for your website. You can create menus that link to "Articles", "Sections" or "Categories". When you open the "Menus" menu select the menu in which you want to add a new item. So, if you pick the main menu for example you will open the list with all the content linked to that menu. Select "New" and you will create a new item for that menu. A list of menu types will appear. So, if you want to make a menu for an uncategorized article, you should better select the "Article layout", for the display of a whole section or category choose the "Section" or "Category" layout and so on.
