Platform Specific Installation Instructions


You need to make sure that Ruby is installed. If it isn’t, consult the documentation of the Linux distribution you are using on how to install it. For example, in case of Ubuntu 17.10 (this should probably also work for any newer Ubuntu version or any recent Debian based distribution) all you need to do is:

sudo apt-get install ruby

Once you have Ruby installed, you need to execute the following command to install kramdown:

sudo gem install kramdown

Mac OS X

Mac OS X Snow Leopard comes with Ruby and Rubygems preinstalled. So installing kramdown is as easy as running:

sudo gem install kramdown


You need to install Ruby first. This can easily be done by using the RubyInstaller - just download the installation binary and run it. After that open a command shell (select Start -> Run..., then enter cmd and click on Ok) and type in the following:

gem install kramdown
