• The synopsis of YAML basic elements is given here: Comments in YAML begins with the (#) character. Comments must be separated from other tokens by whitespaces.

  • Indentation of whitespace is used to denote structure.

  • Tabs are not included as indentation for YAML files.

  • List members are denoted by a leading hyphen (–).

  • List members are enclosed in square brackets and separated by commas.

  • Associative arrays are represented using colon ( : ) in the format of key value pair. They are enclosed in curly braces {}.

  • Multiple documents with single streams are separated with 3 hyphens (—).

  • Repeated nodes in each file are initially denoted by an ampersand (&) and by an asterisk (*) mark later.

  • YAML always requires colons and commas used as list separators followed by space with scalar values.

  • Nodes should be labeled with an exclamation mark (!) or double exclamation mark (!!), followed by string which can be expanded into an URI or URL.
