This is the "SC Entity Index Page" content type. It should only be used in a couple of contexts, the most common being the landing page for a blog feed, as seen below. Generally you do not want to use an index page as a child or sub-page. 

The other common use is setting up a Newsletter landing page. You will use one index page for each particular newsletter issue (which might have blog posts for individual articles and/or a link to a PDF). An additional Newsletter index page (called the newsletter archive) will index theses issues themselves.  

If you have multiple slideshows on your site, an index page can also list all of the slideshows.

More index page instructions can be found on Campfire Community. Always make sure you enter content into the summary field for each blog post, and upload a thumbnail image whenever you can.
