+# Notes
+
+If you plan on using a reverse proxy, you will have to define your domain or subdomain as trusted proxy domain.
+
+The relevant nextcloud configuration file to define this is located at:
+
+````
+/<your-volume-path>/config/www/nextcloud/config/config.php
+````
+
+Adjust the PHP file and put in your subdomains as trusted. Something like this:
+
+````
+<?php
+$CONFIG = array (
+  ...
+  'trusted_domains' => 
+  array (
+    0 => 'nextcloud.example.com',
+    1 => 'nextcloud.anotherdomain.com',
+  ),
+  'dbtype' => 'sqlite3',
+  ...
+);
+````
