+This directory contains prototypes of plugins for JVM, Android, KMP and Swift projects built using "unified" plugins that all utilize a similar model and are implemented using the Declarative DSL.
 
 Currently, these different ecosystems still apply distinct plugins, but those plugins all share a common `plugin-common` dependency, which will gradually grow to contain more functionality.
