YAML data structures are represented by indentation, consecutive items are represented by minus signs, key-value pairs are separated by colons, arrays are enclosed in square brackets, and hashes are
enclosed .
Notes on YAML file format:
- Tab key indentation is not supported, space indentation is required
- Usually indent 2 spaces at the beginning
- Indent 1 space after characters, such as colons, commas, bars
- Annotate with a pound sign
- If it contains special characters, enclose it in single quotes
- Boolean values (true, false, yes, no, on, off) must be enclosed in quotes so that the parser will interpret them as
strings
