# ownCloud 9.0 Server Administration Manual

# Custom Client Download Repositories

You may configure the URLs to your own download repositories for your ownCloud desktop clients and mobile apps in `config/config.php`. This example shows the default download locations:

    <?php

      "customclient_desktop" => "https://owncloud.org/sync-clients/",
      "customclient_android" => "https://play.google.com/store/apps/details?id=com.owncloud.android",
      "customclient_ios"     => "https://itunes.apple.com/us/app/owncloud/id543672169?mt=8",

Simply replace the URLs with the links to your own preferred download repos.

You may test alternate URLs without editing `config/config.php` by setting a test URL as an environment variable:

    export OCC_UPDATE_URL=https://test.example.com

When you’re finished testing you can disable the environment variable:

    unset OCC_UPDATE_URL
