Objective

In this tutorial, we will explore the fundamentals of YAML (YAML Ain't Markup Language) and guide you through the process of building robust and maintainable configuration files. YAML has become a widely adopted format for managing configuration data, offering a human-readable and easy-to-understand syntax. By the end of this tutorial, you will have the knowledge and skills to create YAML configuration files that streamline your application's deployment and management.
