YAML

Human-friendly data format

YAML is a data serialization format used for configuration files and data exchange between programs.

The name stands for "YAML Ain't Markup Language," a recursive acronym emphasizing that it's meant to be human-readable rather than machine-oriented.

YAML uses indentation and simple punctuation instead of brackets or tags: The Docker Compose file is written in YAML.

It's popular in DevOps tools, CI/CD pipelines, and application configuration.
