All you have to do now, is assign the article to some sort of link, like a menu item in your menu, so that it can be accessible. However, because it has the Special Access Level, it will only be viewable with you log in as the administrator. You can test this by logging in as a normal registered user to see if you see the page. You should only see the page in the menu if you log in as the admin and not as any other registered user.
Hope this helps.
