Articles, also known as content, are really the heart of your Joomla! content management system. They are the reason Joomla! exists. In this recipe we'll create an article and assign it a category and section. This will help you as your site grows, and you create more content and make it available.
As you proceed through this, you'll note that many of the settings reference Global. Within Joomla!, you can set specific parameters Globally. That is to say, providing them to all articles the same way. If for instance I ALWAYS want to show the Title in an article, I would set that globally, and simply leave the global setting as is for each article. If I had a specific article that I did not wish to display the Title for I could change that locally for that article only. Changing the title setting in the article from GLOBAL to NO, would accomplish this.
