I learned it when it was first introduced in 2001 so at that time it was known as "Yet Another Markup Language", however the acronym later became a recursive backcronym standing for "'''YAML Ain't Markup Language'''". So, what is it then? Well, it's a data serialization format. It is a superset of JSON, which means that any valid JSON is valid YAML.

Used YAML is used everywhere, such as the [[Ansible]], so refer project. Refer to [https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html as wellAnsible reference appendices YAML Syntax]. If you want to use Ansible, learning YAML first will help you tremendously.
