 nopCommerce Razor MessageService
-===============================
+=========
 
-Extend the core nopCommerce Message Template Engine with Razor-Support (by RazorEngine)
-Works with nopCommerce 3.40
+This Plugin extends the core nopCommerce Message Template Engine with Razor-Support (by [RazorEngine]).
 
+Extend any nopCommerce Message Template with the full power of Razor. It works as a Post-Processor of the Token-Engine, so nothing must be changed. Token will continue to work.
+
+Example of "OrderPlaced.CustomerNotification"
+
+```
+Hello %Order.CustomerFullName%, 
+Thanks for buying from %Store.Name%. Below is the summary of the order. 
+...
+@{
+	if (Model.Order.PaymentMethodSystemName == "Payments.CheckMoneyOrder")
+	{
+		<text>We will send you an Invoice ...</text>
+	}
+	else if (Model.Order.PaymentMethodSystemName == "Payments.PayPalStandard")
+	{
+		<text>You ordered with PayPal. ToDo: Add payment notes here</text>
+	}
+}
+...
+Order Number: %Order.OrderNumber%
+```
+
+Any Message Template has the related Objects available in the Model. E.g. Model.Order, Model.Customer, Model.Vendor etc.
+
+
+Known Issues
+-------
+##### TinyMCE Editor removes <text> Tags and Linebreaks
+###### Workaround:
+Adapt "/Administration/Views/Shared/EditorTemplates/RichEditor.cshtml"
+```
+tinyMCE.init({
+    ...
+	extended_valid_elements: "text",
+	forced_root_blocks: false
+});
+```
