# Documentation Languages

SpecFlow+ LivingDoc parses your feature files looking for keywords, and uses these keywords to format the output. SpecFlow+ LivingDoc supports all languages supported by the official Gherkin parser.

The language used to parse the feature files is determined in the following order:

- The [language specified](https://cucumber.io/docs/gherkin/reference/#spoken-languages) in the Gherkin file itself using the `# language` header
- The language specified in your app.config file (deprecated in SpecFlow 3)
- The language specified in your [build step](Adding-a-Build-Step.md)
- If none of the above apply, SpecFlow+ LivingDoc defaults to en-US
