 <!-- overview -->
 **KYAML** is a safer and less ambiguous subset of YAML, initially introduced in Kubernetes v1.34 (alpha) and enabled by default in v1.35 (beta). Designed specifically for Kubernetes, KYAML addresses common YAML pitfalls such as whitespace sensitivity and implicit type coercion—while maintaining full compatibility with existing YAML parsers and tooling. 
 
 <!-- body -->
+This reference describes KYAML syntax.

 ## Getting started with KYAML
 
 YAML’s reliance on indentation and implicit type coercion often leads to configuration errors, especially in CI/CD pipelines and templating systems like Helm. KYAML eliminates these issues by enforcing explicit syntax and structure, making configurations more reliable and easier to debug.
