Article pages can be used for a variety of purposes. Simply replace this text with your own and you're on your way! Below are some ideas of the type of pages you might build using an article page layout.
Instructional page -- You could write a "how to" page about how to use one of your products, or a technical or sales support document explaining specific features or details about your product or service in more detail.
News or public relations page -- You could use this page to write press releases, news articles, or display copies of articles, news, or other information that has been written about your company, products or services.
Basically, anything purpose that uses a lot of text could be appropriately inserted into this layout. If you want to include an image with your article, you can insert it in the optional space provided, and your text will automatically wrap around it.
