+# Pydantic Support
+
+Hatchet allows for you to optionally validate workflow inputs and step outputs using [Pydantic](https://docs.pydantic.dev/latest/).
+
+### Usage
+
+To enable Pydantic for validation, you'll need to:
+
+1. Provide an `input_validator` as a parameter to your `workflow`.
+2. Add return type hints for your `steps`.
+
+In addition, for improved IDE support and static type checking, you'll need to use `typing.cast` to cast the `workflow_input` and `step_output` to their correct type.
+
+### Example Usage
