See wp:YAML

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.

YAML is used everywhere, such as the Ansible project. Refer to Ansible reference appendices YAML Syntax. If you want to use Ansible, learning YAML first will help you tremendously.
