Introduction
YAML file formats and write precautions
YAML markup language is a very intuitive data serialization format, high readability, similar to the XML data description language, grammar lot simpler than XML.
YAML data structure to represent the continuous item is represented by a minus sign, key-value pairs separated by a colon, enclosed in square brackets array, hash enclosed in braces by indenting.
YAML file format Note:
1. does not support tabs, tab key to indent, you need to use spaces to indent
2. usually begins with two spaces to indent
3. Indent a space character, such as colon, comma, crossbar
4 . Note pound sign
5. If special characters enclosed in single quotes cause
6. Boolean value (true, false, yes, no , on, off) must be enclosed in quotes, so that they will be interpreted as a string parser
