 | Name | Description |
 | ---- | ----------- |
 | `yaml-embedded-languages.include` | Allows the user to include their own languages by providing an object where each key defines the language identifier with regex and the corresponding value specifies the language TextMate `scopeName`. This can be used to add any other language, which could be from another extension. This also allows the user to override any language identifiers currently used for the built-in languages. |
