+# GitLab Pages
+
+With GitLab Pages you can host your website at no cost.
+
+Your files live in a GitLab project's [repository](../repository/index.md),
+from which you can deploy [static websites](#explore-gitlab-pages).
+GitLab Pages supports all static site generators (SSGs).
+
+## Getting Started
+
+Follow the steps below to get your website live. They shouldn't take more than
+5 minutes to complete:
+
+- 1. [Fork](../../../gitlab-basics/fork-project.md#how-to-fork-a-project) an [example project](https://gitlab.com/pages)
+- 2. Change a file to trigger a GitLab CI/CD pipeline
+- 3. Visit your project's **Settings > Pages** to see your **website link**, and click on it. Bam! Your website is live.
+
+_Further steps (optional):_
+
+- 4. Remove the [fork relationship](getting_started_part_two.md#fork-a-project-to-get-started-from) (_You don't need the relationship unless you intent to contribute back to the example project you forked from_).
+- 5. Make it a [user/group website](getting_started_part_one.md#user-and-group-websites)
+
+**Watch a video with the steps above: https://www.youtube.com/watch?v=TWqh9MtT4Bg**
+
+_Advanced options:_
+
+- [Use a custom domain](getting_started_part_three.md#adding-your-custom-domain-to-gitlab-pages)
+- Apply [SSL/TLS certification](getting_started_part_three.md#ssl-tls-certificates) to your custom domain
+
+## Explore GitLab Pages
+
+With GitLab Pages you can create [static websites](getting_started_part_one.md#what-you-need-to-know-before-getting-started)
+for your GitLab projects, groups, or user accounts. You can use any static
+website generator: Jekyll, Middleman, Hexo, Hugo, Pelican, you name it!
+Connect as many custom domains as you like and bring your own TLS certificate
+to secure them.
