As part of the recent "Backdrop LIVE" virtual conference, we hosted a session giving a top-level overview of CiviCRM functionality and integration with Backdrop CMS. If you missed that session but are interested in the topic, you'll be pleased to know that the basic demo and subsequent discussion were recorded. The demo consists of a small Backdrop and CiviCRM site that was built (tongue in cheek) for the town of Pawnee, Indiana. Watch below, and feel free to ask a question about Backdrop or CiviCRM.
