-# DevExpress VCL Reports - Localize the DevExpress Report Viewer and Report Designer
 
-This example localizes DevExpress VCL [Report Viewer](https://docs.devexpress.com/XtraReports/401850/web-reporting/web-document-viewer)/[Report Designer](https://docs.devexpress.com/XtraReports/119176/web-reporting/web-end-user-report-designer) dialogs ([TdxReport](https://docs.devexpress.com/VCL/dxReport.TdxReport) component). German UI localization strings are stored within the project's [Localization](https://github.com/DevExpress-Examples/vcl-reports-localize/tree/25.1.4%2B/Localization) folder as JSON files. You can download UI localizations for additional languages from the [DevExpress Localization Service](https://localization.devexpress.com/).

+This example demonstrates how to localize DevExpress VCL Reports components in Delphi and C++ Builder projects.
+
+The projects in this repository add German localization to DevExpress VCL dialogs:
+[Report Viewer](https://docs.devexpress.com/XtraReports/401850/web-reporting/web-document-viewer) and
+[Report Designer](https://docs.devexpress.com/XtraReports/119176/web-reporting/web-end-user-report-designer).
+Both dialogs are parts of the [DevExpress Reporting Platform](https://docs.devexpress.com/VCL/405469/ExpressReports/vcl-reports),
+which has full support for UI localization.
+
+![Starting screen of the localization example, offering to select between English and German, and to display Report Designer and Report Viewer dialogs](./images/Lokalisierungsbeispiel.png)
+
+## Prerequisites
+
+* Microsoft Windows 10 or newer
+* Embarcadero RAD Studio IDE 12.3 (Athens) or newer (Community Edition is not supported)
+* DevExpress VCL Components v25.2.3 or newer
+* EdgeView2SDK (installed via GetIt Package Manager)
+
+## Implementation Details
+
+Study and build an example project in your preferred development environment:
+
+- [Delphi](./Delphi)
+- [C++ Builder](./CPB)
+
+A compiled application obtains the strings for the German (`de_DE`) locale from the
+[`./Localization/*.de.json`](./Localization) files.
+You can use the [DevExpress Localization Service](https://localization.devexpress.com/) to download localization files for
+German and multiple other locales.
