YAML files

YAML (YAML Ain't Markup Language) is a human-friendly format for organizing and sharing data. It uses plain text with a clear structure of indentation and simple syntax—like lists, key-value pairs, and nested items—making it easy to read and write. YAML is often used in configuration files, data exchange, and automation because it balances readability with the ability to represent complex data structures. Its design emphasizes simplicity, enabling both humans and machines to understand and process the information efficiently.
