In a first step you'll insert the Web-Feed Feed macro into a page where you want to display it. 

If you don't plan to personalize the news according to a user's profile attributes, you can simply define one or more spaces. Entering at least one space name is mandatory. In order for the Corporate News Feed macro to work properly you have to choose a space containing blog posts.

If you want to display the contents of a single Atom or RSS feed, simply enter the respective URL.

The macro also offers the option to display several feeds aggregated to one stream. These groups have to be configured by an admin. For more information on how to do this, please refer to LEN - Define Web Feed Sections for Content Aggregation 2.5.

In addition to the source of your feeds you can define three options:

1. The number of feed items you want to display initially. If there are more items available than the number you define here, the stream will offer a button to load more items. The sorting is chronologically, so newer items will be displayed on top as long as the Atom or RSS feed provides a proper date, which not all feeds do.
2. If you want the links within a news item to open in a new window, check the checkbox "New window".
3. If you don't want to show an excerpt of the feed items' contents, check the checkbox "Show title only".

Save your configuration by clicking on the "Insert" button.
