documentation.js has pluggable output formats: you can get raw documentation as JSON, beautiful, customizable HTML, or Markdown that fits perfectly into an API.md or README.md file in a GitHub repository

documentation.js aims to cover all flavors of modern JavaScript.

documentation.js works in your workflow, whether you just want a command-line utility that generates documentation from your code, you use Gulp to publish websites, or you're building a new system and want low-level JavaScript methods.
