File Extension Details
YAML (which stands for "YAML Ain't Markup Language") is a human-readable data serialization standard that is commonly used for configuration files and in applications where data is being stored or transmitted. The .yml extension (along with .yaml) represents files written in this format. Unlike XML or JSON, YAML emphasizes readability and simplicity, using indentation to define structure rather than braces, brackets, or tags. This makes it highly popular among developers for managing configuration settings in tools like Docker, Kubernetes, GitHub Actions, and various programming language frameworks. YAML supports complex data structures including scalars, sequences (lists), and mappings (hashes/dictionaries). Because it is a plain text format, it can be easily read and edited using any standard text editor, and it is supported by libraries in virtually all major programming languages.
