 ### Programmatic access to the API
 
-Kubernetes officially supports client libraries for [Go](#go-client), [Python](#python-client), [Java](#java-client), [dotnet](#dotnet-client), [JavaScript](#javascript-client), and [Haskell](#haskell-client). There are other client libraries that are provided and maintained by their authors, not the Kubernetes team. See [client libraries](/docs/reference/using-api/client-libraries/) for accessing the API from other languages and how they authenticate.
