YAML

YAML Ain't Markup Language(YAML) is data store language, just like JSON. Instead of brackets, we use indentation for nesting. YAML supports

• Integers
• Floats
• Strings (surrounded with '/"/nothing)
• Boolean
• Arrays (elements are denoted in newlines starting with - like markdown)
• Dictionaries
  in a key:value format.

We can store multiple documents in a single YAML file. The start of a document is denoted with ---.
