-# Rich Text Editor for WinForms - Create a Master-Detail Report
+# Rich Text Editor for WinForms - Use Mail Merge to Create a Master-Detail Report
 
-This example illustrates an older approach to creating master-detail documents.
+This example uses the Rich Text Editor control and its Mail Merge functionality to generate a product catalog report based on a master-detail template.
 
-> [!IMPORTANT]
-> To learn about a newer and more convenient approach to master-detail mail merge, refer to the following article: [Create a Master-Detail Report with a Detail Report Band](https://docs.devexpress.com/XtraReports/4785/create-reports/create-a-master-detail-report-with-a-detail-report-band).
+This project uses a two-level **Categories-Products** data source retrieved from **nwind.xml**.

-This project uses a two-level **Categories-Products** hierarchical data source, retrieved from the **nwind.xml** file. 
+## Implementation Details
 
-![result](./media/96c27986-26f4-4775-b794-285e373adea7.png)
+Rich Text Editor supports master-detail mail merge templates. ``TableStart:Name`` and ``TableEnd:Name`` merge fields define master and nested detail regions. Region names should match group or table names in your data source. 
+
+This example loads the template to the `RichEditControl` instance located in the **Main Template** tab.
+
+![winforms richedit template tab](./media/richedit-template-tab.png)
+
+This example uses the following APIs to specify the data source: 
+
+- [RichEditControl.CreateMailMergeOptions()](https://docs.devexpress.com/OfficeFileAPI/DevExpress.XtraRichEdit.RichEditControl.CreateMailMergeOptions) method - initializes an object with mail merge settings. 
+- [RichEditMailMergeOptions.DataSource](https://docs.devexpress.com/OfficeFileAPI/DevExpress.XtraRichEdit.RichEditMailMergeOptions.DataSource) - sets the data source. 
+- [RichEditControl.MailMerge](https://docs.devexpress.com/OfficeFileAPI/DevExpress.XtraRichEdit.RichEditControl.MailMerge.overloads) method - accepts the settings object as a parameter. 
+
+In this project, the [RichEditControl.MailMerge](https://docs.devexpress.com/OfficeFileAPI/DevExpress.XtraRichEdit.RichEditControl.MailMerge.overloads) method exports the result to the `RichEditControl` instance located in the **Result** tab.
