+The `interface` package provides a system for defining and implementing interfaces in R, with runtime type checking, bringing some of the benefits of statically-typed languages to R with zero dependencies.
+
+`interface` provides:
+
+1. **Interfaces**: Define and implement interfaces with type checking. Interfaces can be extended and nested.
+1. **Typed Functions**: Define functions with strict type constraints.
+1. **Typed Frames**: Choose between a `data.frame` or `data.table` with column type constraints and row validation.
+1. **Enums**: Define and use enumerated types for stricter type safety.
