Publish with [GitBook](https://www.gitbook.com/) in [GitLab](https://about.gitlab.com/)

If you publish it with a CI it takes 30 minutes to build a page with 4 documents.

If you push an already compile web it takes less than a minute.

Create a CI for GitLab as .gitlab-ci.yml inside the repository.

image: alpine:latest
pages:
  stage: deploy
  script:
    - echo 'Nothing to do...'
  artifacts:
    paths:
      - public
  only:
    - master

Remove old builds.

rm -r public/

Build.

gitbook build . public

Remove some garbage.

rm public/{.gitignore,.gitlab-ci.yml}
rm -r _book/

Push to Gitlab.

git add .
git commit -m "Update"
git push origin master
