YAML (YAML Ain't Markup Language)
A human-readable data serialization format often used for configuration files.
YAML (recursive acronym for 'YAML Ain't Markup Language') is designed to be minimal and easy to read. It uses indentation (whitespace) to define structure, unlike XML which uses tags or JSON which uses braces. This makes it very popular for configuration files in modern DevOps tools like Docker (Compose), Kubernetes, and Ansible.
