About YAML

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files. Key features include:

  • Indentation-based structure - Uses whitespace to indicate hierarchy
  • Minimal syntax - No brackets or quotes required for simple values
  • Comments supported - Use # for single-line comments
  • Multi-document support - Multiple documents separated by ---
  • Anchors and aliases - Reuse content with & and * syntax
