 ## Features
 - Supports `System.ComponentModel.DescriptionAttribute` for descriptions.
-- Handles nullable reference types.
+- Handles `Nullable<T>` like `int?` and `nullable reference` types like `string?`.
 - Supports a wide range of types, including primitives (e.g., `bool`, `int`, `double`, `DateTime`).
 - Ensures compatibility with OpenAI's JSON Schema format.

 The following example demonstrates how to generate a JSON Schema using the **LarchSys.OpenAi.JsonSchema** library.
 
 ```csharp
