+========================================================
+Important: #46 - Exclude Stock Handling from Translation
+========================================================
+
+See :issue:`46`
+
+Description
+===========
+
+For each product you can activate the stock management in the backend. Up to now, stock management was carried out
+independently for each language.
+The online shops implemented with the extension sell products with translated product titles and descriptions, but
+not translated products.
+Therefore there should be a collective stock for all translations of a product.
+
+.. IMPORTANT::
+   Check your database for differences in translated products.
+   If any query shows a result, please take a closer look at the products
+   or its backend variants and update them.
+   If you are sure, the respective update query can also be used to adapt
+   the data of the translations to the original language. For different
+   stock levels in the products or their backend variants, this should be
+   compared with the actual stock level.
