Dear community,
unfortunately I can’t maintain Swagger2Markup alone anymore. There are many interesting new topics:
1) Swagger v3 support
2) Fixing bugs
2) Merge Swagger2Markup repositories and create a new multi-module repository.
Any help is welcome.
Kind regards,

The primary goal of this project is to simplify the generation of an up-to-date RESTful API documentation by combining documentation that’s been hand-written with auto-generated API documentation produced by Swagger. The result is intended to be an up-to-date, easy-to-read, on- and offline user guide, comparable to GitHub’s API documentation. The output of Swagger2Markup can be used as an alternative to swagger-ui and can be served as static content.
NOTE: The Swagger Specification has been donated to to the Open API Initiative (OAI) and has been renamed to the OpenAPI Specification.

Swagger2Markup converts a Swagger JSON or YAML file into several AsciiDoc or GitHub Flavored Markdown documents which can be combined with hand-written documentation. The Swagger source file can be located locally or remotely via HTTP. Swagger2Markup supports the Swagger 1.2 and 2.0 specification. Internally it uses the official swagger-parser and my markup-document-builder.

You can use Swagger2Markup to convert your contract-first Swagger YAML file into a human-readable format and combine it with hand-written documentation. As an alternative, you can choose the code-first approach and use Swagger2Markup together with Swagger JAX-RS, springfox or spring-restdocs. If you are Gradle or Maven user, you can also use the Swagger2Markup Gradle Plugin or Swagger2markup Maven Plugin.

AsciiDoc is preferable to Markdown as it has more features. AsciiDoc is a text document format for writing documentation, articles, books, ebooks, slideshows, web pages and blogs. AsciiDoc files can be converted to HTML, PDF and EPUB. AsciiDoc is much better suited for describing public APIs than JavaDoc or Annotations.

You can generate your HTML5, PDF and EPUB documentation via asciidoctorj or even better via the asciidoctor-gradle-plugin or asciidoctor-maven-plugin.

The project requires at least JDK 8.
