Backdrop CMS configuration files and Git: The versioned staging approach
There are lots of different approaches to managing Backdrop CMS configuration files in Git, but this one is my favorite. It works great for projects with multiple developers, and it can also be easily adapted for multiple deployment environments, as on Pantheon.
This versioned staging directory strategy has been adapted from a recommendation from @populist and @davidstrauss based on how the
config directory is being managed for Drupal 8/9/10 on Pantheon.
