 ## Introduction
+This is a markdown file, click Ctrl+Shift+V to view or click open preview.
 
 This guide provides an overview of Python’s built-in types, explains how and why to use type hints, and demonstrates how to leverage the `typing` module and MyPy for static type checking. Whether you’re new to type annotations or looking to adopt a more robust workflow, you’ll find examples and best practices for writing clearer, safer, and more maintainable Python code.
