Using editorial pages as news articles
If your news module has been configured to use editorial pages as news articles you can create and edit news articles in the same way that you create and edit any other editorial page.
The news module will have defined a page as the root page for the news articles. This root page is usually given a 'news page' content layout and acts as the menu page for the series of news articles. All child pages below this root page will automatically be displayed as news articles.
New news pages are created by adding new editorial pages below the root page on the tree. These pages can be managed, edited and deleted in the same way as any other editorial page.
The News as Pages help article describes this process in detail.
