 ## Overview
 This is the swagger codegen project, which allows generation of API client libraries (SDK generation), server stubs and documentation automatically given an [OpenAPI Spec](https://github.com/OAI/OpenAPI-Specification). Currently, the following languages/frameworks are supported:
 
-- **API clients**: **ActionScript**, **C#** (.net 2.0, 4.0 or later), **C++** (cpprest, Qt5, Tizen), **Clojure**, **Dart**, **Go**, **Groovy**, **Haskell**, **Java** (Jersey1.x, Jersey2.x, OkHttp, Retrofit1.x, Retrofit2.x, Feign), **Node.js** (ES5, ES6, AngularJS with Google Closure Compiler annotations) **Objective-C**, **Perl**, **PHP**, **Python**, **Ruby**, **Scala**, **Swift** (2.x, 3.x), **Typescript** (Angular1.x, Angular2.x, Fetch, Node)
