+# GitLab private Maven repository administration
+
+> **Notes:**
+- [Introduced][ee-5811] in GitLab 11.3.
+- This document is about the admin guide. Learn how to use GitLab Maven 
+  repository from [user documentation](../user/project/maven_packages.md).
+
+When enabled, every project in GitLab will have its own space to store Maven packages.
+
+## Enable the Maven repository
+
+**Omnibus GitLab installations**
+
+# TODO: Update this section once https://gitlab.com/gitlab-org/gitlab-ee/issues/7253 is resolved
+
+**Installations from source**
+
+If you have installed GitLab from source:
+
+1. After the installation is complete, you will have to configure the `packages` 
+   section in `gitlab.yml` in order to enable it.
+
+The contents of `gitlab.yml` are:
+
+```
+packages:
+  enabled: true
+```
+
+where:
+
+| Parameter | Description |
+| --------- | ----------- |
+| `enabled` | `true` or `false`. Enables the packages repository in GitLab. By default this is `false`. |
