+
+Configuration
+=============
+
+To configure a language dependent attachment:
+
+#. Activate the developer mode;
+#. go to *Settings > Technical > Email > Templates*;
+#. go to the form view of the template you want to change;
+#. change the field *Language Dependent Attachments* to what you want.
+
+Usage
+=====
+
+When a template is selected in the mail composer, the attachments will be automatically added based on the recipients language.
+The language of the recipients can be configured on the Partner form view.
+When partners with different languages are selected all attachments of the partners languages will be added.
+
+To use the functionality:
+
+#. Configure a template (e.g. the sale order mail template)
+#. go to a sale order;
+#. click *Send by Email*;
+#. the attachments are added based on the customer's language.
