+size of your application once you are ready to ship. Visit https://aka.ms/wct/optimize to learn more.
+
+You can find out more about the Windows Community Toolkit at https://aka.ms/windowstoolkit
+Or even try our controls in our sample app at https://aka.ms/windowstoolkitapp
+Docs are available here: https://aka.ms/windowstoolkitdocs
+
+The Windows Community Toolkit is made possible by our developer community!
+Every contribution made to the Toolkit helps everyone, to learn how to contribute visit https://aka.ms/wct/wiki
+
+----
+
+This package also depends on the WinUI library, so you'll need to set XamlControlsResources as your Application resources in App.xaml:
+
+    <Application>
+        <Application.Resources>
+            <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
+        </Application.Resources>
+    </Application>
+
+If you have other resources, then we recommend you add those to the XamlControlsResources' MergedDictionaries.
+This works with the platform's resource system to allow overrides of the XamlControlsResources resources.
+
+<Application
+    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+    xmlns:controls="using:Microsoft.UI.Xaml.Controls">
+    <Application.Resources>
+        <controls:XamlControlsResources>
+            <controls:XamlControlsResources.MergedDictionaries>
+                <!-- Other app resources here -->
+            </controls:XamlControlsResources.MergedDictionaries>
+        </controls:XamlControlsResources>
+    </Application.Resources>
+</Application>
+
+See http://aka.ms/winui for more information about the WinUI library.
