 ## API Overview
 
 The API provided by `yaml` has three layers, depending on how deep you need to go: [Parse & Stringify](https://eemeli.org/yaml/#parse-amp-stringify), [Documents](https://eemeli.org/yaml/#documents), and the underlying [Lexer/Parser/Composer](https://eemeli.org/yaml/#parsing-yaml).
