+## GitLab CI
+
+This project's static Pages are built by [GitLab CI][ci], following the steps
+defined in [`.gitlab-ci.yml`](.gitlab-ci.yml):
+
+```
+pages:
+  stage: deploy
+  script:
+  - mkdir .public
+  - cp -r * .public
+  - mv .public public
+  artifacts:
+    paths:
+    - public
+  only:
+  - master
+```
+
+## 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 that you have wrongly set up the CSS URL in your
+   HTML files.
