-## GitLab CI
-
-This project's static Pages are built by [GitLab CI][ci], following the steps
-defined in [`.gitlab-ci.yml`](.gitlab-ci.yml):
-
-```yaml
-# requiring the environment of NodeJS 10
-image: node:10
-
-# add 'node_modules' to cache for speeding up builds
-cache:
-  paths:
-    - node_modules/ # Node modules and dependencies
-
-before_script:
-  - npm install gitbook-cli -g # install gitbook
-  - gitbook fetch 3.2.3 # fetch final stable version
-  - gitbook install # add any requested plugins in book.json
-
-test:
-  stage: test
-  script:
-    - gitbook build . public # build to public path
-  only:
-    - branches # this job will affect every branch except 'master'
-  except:
-    - master
-    
-# the 'pages' job will deploy and build your site to the 'public' path
-pages:
-  stage: deploy
-  script:
-    - gitbook build . public # build to public path
-  artifacts:
-    paths:
-      - public
-    expire_in: 1 week
-  only:
-    - master # this job will affect only the 'master' branch
-```
-
-## Building locally
-
-To work locally with this project, you'll have to follow the steps below:
-
-1. Fork, clone or download this project
-1. [Install][] GitBook `npm install gitbook-cli -g`
-1. Fetch GitBook's latest stable version `gitbook fetch latest`
-1. Preview your project: `gitbook serve`
-1. Add content
-1. Generate the website: `gitbook build` (optional)

-
-Read more at GitBook's [documentation][].
-
-## GitLab User or Group Pages
-
-To use this project as your user/group website, you will need one additional
-step: just rename your project to `namespace.gitlab.io`, where `namespace` is
-your `username` or `groupname`. This can be done by navigating to your
-project's **Settings**.
-
-Read more about [user/group Pages][userpages] and [project Pages][projpages].
-
-## Did you fork this project?
-
-If you forked this project for your own use, please go to your project's
-**Settings** and remove the forking relationship, which won't be necessary
-unless you want to contribute back to the upstream project.
-
-## Troubleshooting
-
-1. CSS is missing! That means two things:
-
-    Either that you have wrongly set up the CSS URL in your templates, or
-    your static generator has a configuration option that needs to be explicitly
-    set in order to serve static assets under a relative URL.
