YAML 1.1

YAML 1.1 is a human-readable data serialization format used for configuration files and data exchange between languages. It's designed to be easy to read and write, featuring a simple structure based on indentation and key-value pairs. In YAML, data is organized in a hierarchy, allowing for lists and nested items, making it flexible for various use cases. It is commonly used in applications like Docker, Kubernetes, and Ansible for its clarity and ease of editing. YAML 1.1 introduced certain features like support for complex data types and improved handling of mismatched line endings.
