+# MbSoftLab.TemplateEngine.Core.Razor
+
+Optionales Erweiterungspaket für MbSoftLab.TemplateEngine.Core, das die `RazorTemplateEngine<T>` bereitstellt.
+
+## Installation
+
+```bash
+# .NET CLI
+dotnet add package MbSoftLab.TemplateEngine.Core.Razor
+
+# Oder Projekt-Referenz (Monorepo)
+dotnet add <IhrProjekt>.csproj reference MbSoftLab.TemplateEngine.Core.Razor/MbSoftLab.TemplateEngine.Core.Razor.csproj
+```
+
+## Verwendung
+
+```csharp
+using MbSoftLab.TemplateEngine.Core;
+
+public class Person : TemplateDataModel<Person>
+{
+    public string FirstName { get; set; }
+}
+
+var person = new Person { FirstName = "Anna" };
+
+var engine = new RazorTemplateEngine<Person>();
+engine.TemplateString = "<h1>@Model.FirstName</h1>";
+string html = engine.CreateStringFromTemplate(person);
+```
+
+Hinweis: `TemplateDataModel<T>` ist nun eine einfache Klasse im Core (ohne Razor-Basis). Die Razor-Engine erhält intern `Model` als Datenmodell (`template.Run(TemplateDataModel?.Model)`).
