News entries are created and edited by going to Entries > News. Once there you can edit an existing entry by clicking it's title or creating a new entry by clicking the New Entry button at the top right.
News entries are displayed in reverse chronological order on the news landing page. To change the order of an entry here you would edit the Post Date in the top right of the publish page.
Each news entry has a Post Image that is displayed at the top of the page. This should be 1860px * 600px minimum size. This image will be resized automatically for smaller devices when needed.
You can also add a category to a news item by clicking the Add a Category button. This will open a pop-up where you can select from existing categories or add/delete categories.
The summary field is used on the news landing page below the Post Image, but is not used on the main news entry.
Similar to the homepage there is an option to add blocks of content. For news entries there are three block types.
