 All existing export modules can be accessed with the `ExportManager` Plugin.
 You can specify your own CSS file within the `app.json` `exports -> pdf -> css` setting (full path) - the default is `api/v1/class/exports/modules/PDFExportModule/css/index.css`
 
+### Custom contents
+
+You can use custom contents within your PDF exports by placing HTML/PHP files into `api/v1/class/exports/modules/PDFExportModule/php/`.
+Two files can be placed there:
+
+- `user_content_ending.php`: This file is included at the end of the PDF export, e.g. for signatures or custom footers
+- `user_content_starting.php`: This file is included at the beginning of the PDF export, e.g. for custom headers.
+You can put normal PHP and HTML code into these files.
+
 ## QR codes
 
 You can use the plugin `QRClock` to generate QR codes for yourself to either clock in or out. The QR code generated can be saved for later use, e.g. print it out.
