+# Instance-level Template Repository
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/5986) in
+> [GitLab Premium](https://about.gitlab.com/pricing) 11.3.
+
+## Overview
+
+In hosted systems, enterprises often have a need to share their own templates
+across teams. This feature allows an administrator to pick a project to be the
+instance-wide collection of templates. These templates are then exposed to all
+users while the project remains secure. Currently supported templates: Licenses.
+
+## Configuration
+
+An administrator can choose any project to be the template repository. This is
+done through the `Settings` page in the `Admin Area` or through the API. On the
+`Settings` page, there is a `Templates` section with a selection box for
+choosing a project:
+
+![](img/file_template_admin_area.png)
+
+
+Once a project has been selected you can add custom templates to the repository,
+and they will appear in the appropriate places in the frontend and API.
+Templates must be added to a specific subdirectory in the repository,
+corresponding to the kind of template. They must also have the correct extension
+for the template type.
+
+Currently, only custom license templates are supported. This must go in the
+`LICENSE/` subdirectory, and must have `.txt` file extensions. So, the hierarchy
+should look like this:
+
+```text
+|-- README.md
+|-- LICENSE
+    |-- custom_license.txt
+    |-- another_license.txt
+```
+
+Once this is established, the list of `Custom` licenses will be included when
+creating a new file and the file type is `License`. These will appear at the
+bottom of the list:
+
+![](img/file_template_user_dropdown.png)
+
+If this feature has been disabled or no licenses are present, then there will be
+no `Custom` section in the selection dropdown.
