YAML (YAML Ain't Markup Language) is a human-friendly data serialization format. It uses indentation for structure and is widely used for config files (Docker Compose, Kubernetes, GitHub Actions).

Is YAML a superset of JSON?

Yes — any valid JSON is valid YAML 1.2. You can paste JSON directly and it will parse correctly as YAML.
