Let's look at the steps required to publish your first article:
Navigate to Content | Article Manager (alternatively you can use the Article Manager quick icon in the Control Panel).
In the toolbar, click on the New button (the green one with the plus sign).
Alternatively, you can use the fly-out menu Content | Article Manager | Add New article. This will take you to the Article Manager: Add New Article screen even faster.
In the Article Manager: Add New Article screen, fill out the Title field as shown in the following screenshot. Enter a title (for example, My first article) and add some article text in the text editor box. Any text will do; for now we're just playing around in the example site.
Leave the Category drop-down box as it is: it's okay to have this article assigned to the Sample Data-Articles category. You'll learn how to create categories and organize content in the next two chapters.
Make sure Status (under Details) is set to Published...
