+# PDF Documents - compatibility layer
+
+Compatibility Layer for PDF Documents Module to OXID InvoicePDF Module
+
+This customization allows third party modules that would otherwise use the OXID InvoicePdf module for their own purposes, to use the D3 PDF Documents module instead.
+
+The generation call of the standard documents (invoice, delivery note) is routed via the PDF Documents module.
+
+If further documents have been added, the routing must be added there.
+
+The admin form for document generation is not copied here, because it is already included in the PDF Documents module in a similar form. Adjustments (e.g. template block overloads) should be adapted to this.
+
+## System requirements:
+
+- installed OXID eShop from version 6.1
+- D3 PDF Documents Module
+- PHP version for which installation packages are available (PHP 7)
+- Installation via Composer
+
+## compatibility:
+
+The module contains the same functionality as the `OXID Invoice PDF` module. Since it is intended to replace its function, the OXID module is uninstalled.
+
+## Installation 
+
+Disable the OXID InvoicePDF module in the admin area of your shop.
+
+```bash
+composer require d3/pdfdocuments_compat --update-no-dev
+```
+
+Delete the files of the OXID InvoicePDF module.
