I need diagrams in asciidoc, then I have installed asciidoctor-diagram as explained here. Then, the documentation requires:



You can install the Asciidoctor Diagram gem by typing gem install in the CLI.

    $ gem install asciidoctor-diagram

by first adding the following entry to your project’s Gemfile.
Gemfile

    gem 'asciidoctor-diagram'

Then execute bundle in the CLI.

    $ bundle

But I have only an asciidoc file, what is this "project's Gemfile" I am supposed to have?
Needless to say I don't know ruby.
