YAML

ELI5 — The Vibe Check

YAML is a way to write structured data that actually looks like a human wrote it. No curly braces, no quotation marks everywhere — just indentation and colons. It's the config file format of choice for DevOps tools like Docker and Kubernetes.

Real Talk

YAML (YAML Ain't Markup Language) is a human-readable data serialisation format. It uses indentation to represent hierarchy and is widely used for configuration files, CI/CD pipelines, and infrastructure-as-code. It is a superset of JSON.
