The Index Pages system allows you to designate pages as the index page for a particular post type.
This allows you to have a custom title, text content, and other information displayed on your
post type archives, should your current theme support it.
For theme developers, the plugin offers some template functions for loading the post object for the
current index page (including the posts page), in a similar fashion to
the_post();, to create things
like a customizable introductory banner that appears above the listing, using the index page’s data.
Designated index pages are flagged as such in the Pages manager, for easy recognition.
