 # Custom instance-level project templates **(PREMIUM ONLY)**
 
 > [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/6860) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.2.
 
-When you create a new [project](../project/index.md), creating it based on custom project templates is
-a convenient bootstrap option.
+GitLab administrators can configure the group where all the custom project
+templates are sourced.
 
-GitLab administrators can configure a GitLab group that serves as template
-source for an entire GitLab instance under **Admin area > Settings > Custom project templates**.
+Every project directly under the group namespace will be
+available to the user if they have access to them. For example:
+
+- Public project in the group will be available to every logged in user.
+- Private projects will be available only if the user is a member of the project.
+
+Repository and database information that are copied over to each new project are
+identical to the data exported with
+[GitLab's Project Import/Export](../project/settings/import_export.md).
 
 NOTE: **Note:**
 To set project templates at a group level,
 see [Custom group-level project templates](../group/custom_project_templates.md).
 
-Within this section, you can configure the group where all the custom project
-templates are sourced. Every project directly under the group namespace will be
-available to the user if they have access to them. For example, every public
-project in the group will be available to every logged in user.
+## Configuring
 
-However, private projects will be available only if the user is a member of the project.
+GitLab administrators can configure a GitLab group that serves as template
+source for an entire GitLab instance by:
+
+1. Navigating to **Admin area > Settings > Templates**.
+1. Expanding **Custom project templates**.
+1. Selecting a group to use.
+1. Pressing **Save changes**.
 
 NOTE: **Note:**
 Projects below subgroups of the template group are **not** supported.
