-## Custom project templates **[PREMIUM ONLY]**
+## Project templates
+
+Project templates can pre-populate your project with necessary files to get you started quickly.
+
+There are two types of project templates:
+
+- [Built-in templates](#builtin-templates), sourced from the [`project-templates`](https://gitlab.com/gitlab-org/project-templates) group.
+- [Custom project templates](#custom-project-templates-premium-only), for custom templates configured by GitLab administrators and users.
+
+### Built-in templates
+
+Built-in templates are project templates that are:
+
+- Developed and maintained in the
+  [`project-templates`](https://gitlab.com/gitlab-org/project-templates) group.
+- Released with GitLab.
+
+To use a built-in template on the **New project** page:
+
+1. On the **Create from template** tab, select the **Built-in** tab.
+1. From the list of available built-in templates, click the:
+    - **Preview** button to look at the template source itself.
+    - **Use template** button to start creating the project.
+1. Finish creating the project by filling out the project's details. The process is the same as for
+   using a [blank project](#blank-projects).
+
+TIP: **Tip:**
+You can improve the existing built-in templates or contribute new ones on the
+[`project-templates`](https://gitlab.com/gitlab-org/project-templates) group.
