I'm setting up a site with several channels, and the design requires an introductory paragraph at the top of each channel's index page (ie. before the list of entries) - essentially a post that corresponds to the channel's index page.
As I understand it, there's only a template but no entry corresponding to the index of a channel, so I'm wondering how best to handle this in Craft. I definitely don't want it hard-coded in the template, and ideally it should be somewhere reasonably intuitive for site admins to find and edit.
It feels like it should be straightforward to implement, but I just can't quite think how to do it. Any suggestions would be much appreciated!
