GitLab

GitLab CI/CD can render your documentation and publish it with GitLab Pages. Add this .gitlab-ci.yml to the root of your repository; it publishes when files under docs/ change on the default branch:

pages:
  stage: deploy
  image: mcr.microsoft.com/dotnet/sdk:10.0
  script:
    - dotnet tool install mdu --tool-path .tools
    - .tools/mdu render docs public
  pages:
    publish: public
  rules:
    - if: '$CI_PIPELINE_SOURCE == "push" && $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH'
      changes:
        - docs/**/*

GitLab publishes the generated public folder; since GitLab 17.10 it is included as a job artifact automatically. Make sure a GitLab Runner is enabled for the project.
