 ## Features
 
+- [Type-Safe](#recursive-hydration): Type-safety is enforced by the PHP language itself. No need to validate a type.
 - [Non-Invasive](#hydrating-from-data): Simply add the DataModel trait to a class. No need to extend, implement, or construct.
 - [Recursive Instantiation](#recursive-hydration): Recursively instantiate classes based on their type.
 - [Type Casting](#property-level-cast): Supports primitives, custom classes, enums, and more.
