YAML Indentation Explained
Indentation is the heart of YAML. Getting it right is most of getting YAML right.
Spaces define nesting
Each level of nesting is one consistent indentation step deeper, using spaces only. The amount must be consistent within a block, which is why a single misaligned line breaks structure.
No tabs allowed
YAML forbids tabs for indentation. An editor that inserts tabs is a frequent source of errors; configure it to use spaces for YAML files.
