In my last post in this series, I started going down the theming rabbit hole for Backdrop. A lot of that was very similar to my experience with Drupal 7 (D7), but separating the regions from the theme files was a really nice addition.
Now, we are going to dive into more of a back-end-related discussion. To do so, we'll be converting the XML Sitemap module to be able to run on Backdrop. It was the most popular module I could see, other than CTools, that hadn't been ported to Backdrop. Since it has no dependencies, I thought it would be good for me to start on this one.
