Default YAML spec version is `1.2`, it can be changed with `yaml.yamlVersion` setting.\n\n## Features\n\n1. YAML validation:\n   - Detects whether the entire file is valid yaml\n2. Validation:\n   - Detects errors such as:\n     - Node is not found\n     - Node has an invalid key node type\n     - Node has an invalid type\n     - Node is not a valid child node\n   - Detects warnings such as:\n     - Node is an additional property of parent\n3. Auto completion:\n   - Auto completes on all commands\n   - Scalar nodes autocomplete to schema\u0027s defaults if they exist\n4. Hover support:\n   - Hovering over a node shows description _if available_\n5. Document outlining:\n   - Shows a complete document outline of all nodes in the document\n\n## Language Server Settings\n\nThe following settings are supported:\n\n- `yaml.yamlVersion`: Set default YAML spec version (1.2 or 1.1)\n- `yaml.format.enable`: Enable/disable default YAML formatter (requires restart)\n- `yaml.format.singleQuote`: Use single quotes instead of double quotes\n- `yaml.format.bracketSpacing`: Print spaces between brackets in objects\n- `yaml.format.proseWrap`: Always: wrap prose if it exceeds the print width, Never: never wrap the prose, Preserve: wrap prose as-is\n- `yaml.format.printWidth`: Specify the line length that the printer will wrap on\n- `yaml.validate`: Enable/disable validation ",
