YAML or ‘Yet Another Markup Language’ is a human-readable data serialization language. It is designed in order to be both human-readable and also efficient for parsing.
The YAML specification was written in 2006 by David Preshing, the creator of PHP Markdown, who wanted a universal markup language that was easy for humans to read and write, but still allowed for significant information density and reasonable balancing of tradeoffs between the machine time required to process it and the machine time required to produce it.
