# YAML Cheat Sheet ### YAML example ```yaml # Comments in YAML look like this key: value another_key: Another value goes here. a_number_value: 100 # Nesting uses indentation. 2 space indent is preferred (but not required). a_nested_map: key: value another_key: Another Value another_nested_map: hello: hello # Sequences (equivalent to lists or arrays) look like this # (note that the '-' counts as indentation): a_sequence: - Item 1 - Item 2 # Since YAML is a superset of JSON, you can also write JSON-style maps and sequences: json_map: {"key": "value"} json_seq: [3, 2, 1, "takeoff"] ``` Checking YAML files' formatting can be done using `yamllint`
