-When you create a new [project](../project/index.md), creating it based on custom project templates is
-a convenient option.
+Custom project templates are useful for organizations that need to create many similar types of [projects](../project/index.md) and want to start from the same jumping-off point.
+
+## Setting up Group-level Project Templates
+
+To use a custom project template for a new project you need to:
+
+1. [Create a 'templates' subgroup](subgroups/index.md).
+1. [Add repositories (projects) to the that new subgroup](index.md#add-projects-to-a-group), as your templates.
+1. Edit your group's settings to look to your 'templates' subgroup for templates:
+   1. In the left-hand menu, click **{settings}** **Settings > General**.
+
+      NOTE: **Note:**
+      If you don't have access to the group's settings, you may not have sufficient privileges (for example, you may need developer or higher permissions).
+
+   1. Scroll to **Custom project templates** and click **Expand**. If no **Custom project templates** section displays, make sure you've created a subgroup, and added a project (repository) to it.
+   1. Select the 'templates' subgroup.
+
+### Example structure
+
+Here is a sample group/project structure for a hypothetical "Acme Co" for project templates:
+
+```txt
+# GitLab instance and group
+gitlab.com/acmeco/
+    # Subgroups
+    internal
+    tools
+    # Subgroup for handling project templates
+    websites
+        templates
+            # Project templates
+            client-site-django
+            client-site-gatsby
+            client-site-hTML
+
+        # Other projects
+        client-site-a
+        client-site-b
+        client-site-c
+        ...
+```
+
+### Adjust Settings
 
 Users can configure a GitLab group that serves as template
 source under a group's **Settings > General > Custom project templates**.
