- Supports file inclusion for markdown files (which GitHub refuses to do). That means your markdown file can include other files: more markdown, highlighted code, etc.
- Can insert a table of contents into your markdown page.
You don't need to code in Ruby to use
markdown_helper. You only need to have Ruby installed, which is the default on many Linux installations.
ruby --version. If that succeeds, you already have Ruby installed.
All you need do now is type
gem install markdown_helper, and you're ready to use the CLI.
