The record

Purpose: Swagger2Markup combines hand-written material with generated API documentation to produce REST API guides.
Input and output: It converts Swagger JSON or YAML into AsciiDoc, GitHub Flavored Markdown, or Atlassian Confluence Wiki documents.
Input location: The Swagger source file can be local or accessible remotely over HTTP.
Conversion options: The converter can write output to a folder, write a single file, or return documentation as a string.
Integrations: The documentation describes use with Swagger JAX-RS, Springfox, Spring REST Docs, and Gradle or Maven plugins.
Customization: It provides extension points for overview, paths, security, and definitions documents, and for modifying the Swagger model before conversion.
Generated documentation: By default, it generates four AsciiDoc files for overview, paths, security, and definitions, and can instead produce one file or a string.
Formats: The documentation says AsciiDoc output can be converted to HTML, PDF, and EPUB using Asciidoctor tools.
Compatibility limit: The project README says it supports Swagger 1.2 and 2.0 specifications and requires at least JDK 8.
Maintenance: The README says the maintainer can no longer maintain the project alone and lists Swagger v3 support and bug fixes among topics needing help.
License: The project is licensed under Apache License 2.0.
Support: The README directs users to Gitter for questions and invites bug reports through GitHub issues and enhancements through pull requests.
