Install and Update

To simplify installation, Asciidoctor is packaged and published as a RubyGem to the package repository at It’s also distributed as a package for popular Linux distributions and macOS.

In addition to running on Ruby, Asciidoctor can be executed on a JVM using AsciidoctorJ or in any JavaScript environment (including the browser) using Asciidoctor.js.

Installation methods

Asciidoctor can be installed using:

  • Bundler,

  • the package manager for popular Linux distributions,

  • Homebrew or MacPorts for macOS,

  • the gem install command (recommended for Windows users), or

  • the Asciidoctor Docker image

Bundler is the preferred method of installation as it keeps the gems scoped to your project or workspace. However, it does not make the asciidoctor command globally available in your terminal. That’s when a package manager is more appropriate. The benefit of using your operating system’s package manager to install the gem is that it adds the asciidoctor command to your PATH and it handles installing Ruby and the RubyGems library if those packages are not already installed on your machine. On the other hand, if you’re familiar with Docker, using the Asciidoctor Docker image gives you the best isolation from your system.

You should use the same method to update and uninstall Asciidoctor as you use to install it.
