 # Import multiple repositories by uploading a manifest file
 
-GitLab allows you to import all the required git repositories 
-based a manifest file like the one used by the [Android repository](https://android.googlesource.com/platform/manifest/+/2d6f081a3b05d8ef7a2b1b52b0d536b2b74feab4/default.xml).

+## Requirements
 
->**Note:** 
-This feature requires [subgroups](../../group/subgroups/index.md) to be supported by your database. 
+GitLab must be using PostgreSQL for its database, since
+[subgroups](../../group/subgroups/index.md) are needed for the manifest import
+to work.
 
-You can do it by following next steps:

+## Manifest format
 
-![Manifest upload](img/manifest_upload.png)
+A manifest must be an XML file. There must be one `remote` tag with a `review`
+attribute that contains a URL to a Git server, and each `project` tag must have
+a `name` and `path` attribute. GitLab will then build the URL to the repository
+by combining the URL from the `remote` tag with a project name.
+A path attribute will be used to represent the project path in GitLab.
