+This directory contains sources for the "new" plugin system introduced circa
+2024, which is the replacement for the "prototype" plugin system introduced
+circa 2017. The sources for the "prototype" plugin system are located in
+`../plugin`.
+
+The "new" plugin system is partially based on the "prototype" plugin system. As
+the "prototype" plugin system becomes deprecated and unsupported, any features
+that the "new" plugin system relies on can be migrated to this directory.
