In the windows menu look for Start Command Prompt with Ruby and execute the following commands:
$ gem install asciidoctor $ gem install asciidoctor-diagram OR: gem install asciidoctor-kroki $ gem install asciidoctor-pdf
For RAT: Generation of the diagrams will either take place via the ruby gem asciidoctor-diagram or asciidoctor-kroki. This can be configured via a documentr variable. asciidoctor-diagram requires java and graphviz and asciidoctor-kroki requires communication to a kroki server.

$ gem install --force --local bundler-2.5.7.gem
2. Download our ready-made Bundler package for local (offline) installation containing all necessary gems. Extract the archive to a local directory.
3. Run the following command from the above directory where the Gemfile, Gemfile.lock and the /vendor/cache/ subdirectory are available:
$ bundle install --local
