antora VS markdown-live-preview

Unlike docToolchain or Asciidoctor, Antora is a true framework for Asciidoc that can store, retrieve, and aggregate all Asciidoc content from multiple git repositories. Antora’s page referencing system isn’t coupled to filesystem paths or URLs. You are able to cross reference pages across a local machine, a staging environment, and a production environment. To generate a site with Antora, you need the Antora CLI and Antora site generator.
