          %ul
            %li
              %b Integrated:
              GitLab CI/CD is part of GitLab. You can use it for free on
              %a{href: "https://gitlab.com/"} GitLab.com
            %li
              %b Easy to learn:
              See our
              %a{href: "https://docs.gitlab.com/ee/ci/quick_start/"} Quick Start
              guide
            %li
              %b Beautiful:
              GitLab CI/CD offers the same great experience as GitLab. Familiar, easy to use, and beautiful.
            %li
              %b Scalable:
              Tests run distributed on separate machines of which you can add as many as you want
            %li
              %b Faster results:
              Each build can be split in multiple jobs that run in parallel on multiple machines
            %li
              %b Continuous Delivery (CD):
              multiple stages, manual deploys,
              %a{href: "https://docs.gitlab.com/ee/ci/environments.html"} environments,
              and
              %a{href: "https://docs.gitlab.com/ee/ci/variables/"} variables
            %li
              %b Open source:
              CI/CD is included with both the open source GitLab Community Edition and the proprietary GitLab Enterprise Edition

            %li
              %b Multi-platform:
              you can execute builds on Unix, Windows, macOS, and any other platform that supports Go.
            %li
              %b Multi-language:
              build scripts are command line driven and work with Java, PHP, Ruby, C, and any other language.
            %li
              %b Stable:
              your builds run on a different machine than GitLab.
            %li
              %b Parallel builds:
              GitLab CI/CD splits builds over multiple machines, for fast execution.
