+# Continuous deployment with GitLab
+
+## Introduction
+
+In this tutorial, we will use [GitLab](https://gitlab.com/) to build, deploy, and host a [Hugo](https://gohugo.io/) site. With Hugo and GitLab, this is incredibly easy.
+
+It is assumed that you know how to use git for version control and have a GitLab account, and that you have gone through the [quickstart guide]({{< relref "overview/quickstart.md" >}}) and already have a Hugo site on your local machine.
+
+
+## Create .gitlab-ci.yml
+
+```bash
+cd your-hugo-site
+```
+
+In the root directory of your Hugo site, create a `.gitlab-ci.yml` file. The `.gitlab-ci.yml` configures the GitLab CI on how to build your page. Simply add the content below.
+
+```yml
+image: publysher/hugo
+
+pages:
+  script:
+  - hugo
+  artifacts:
+    paths:
+    - public
+  only:
+  - master
+```
+
+## Push Hugo site to GitLab
+Next up, create a new repository on GitLab. It is *not* necessary to set the repository public. In addition, you might want to add `/public` to your .gitignore file, as there is no need to push compiled assets to GitLab.
+
+```bash
+# initialize new git repository
+git init
+
+# add /public directory to our .gitignore file
+echo "/public" >> .gitignore
+
+# commit and push code to master branch
+git add .
+git commit -m "Initial commit"
+git remote add origin https://gitlab.com/YourUsername/your-hugo-site.git
+git push -u origin master
+```
+
+## Wait for your page to be built
+That's it! You can now follow the CI agent building your page at https://gitlab.com/YourUsername/your-hugo-site/pipelines.
+After the build has passed, your new website is available at https://YourUsername.gitlab.io/your-hugo-site/
+
+## Suggested next steps
+
+GitLab supports using custom CNAME's and TLS certificates, but this is out of the scope of this tutorial. For more details on GitHub Pages, see [https://about.gitlab.com/2016/04/07/gitlab-pages-setup/](https://about.gitlab.com/2016/04/07/gitlab-pages-setup/)
