What is the YAML file format?

YAML stands for Yet Another Markup Language, it is a human-readable data serialization language that is commonly used for writing configuration files and transferring data between applications.

YAML has a simple and intuitive syntax that can represent structured and semi-structured data, such as lists, dictionaries, scalars, and collections. It is also a superset of JSON, which means that any valid JSON file is also a valid YAML file.

YAML files usually have the extension .yml or .yaml.
