-# Fixed version usage
-If you want to ship a fixed version of the WebView2 runtime with your application you will need to include it in your project.
-
-Instructions can be found at: https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution
-
-The following assume you are using runtime version 95.0.1020.53, you will change this number to whatever version you are using.
-
-You will need to:
-1 Include the fixed WebView2 runtime in the package project
-<pre>\WebView2_WinUI3_Sample\WebView2_WinUI3_Sample (Package)\FixedRuntime\95.0.1020.53\</pre>
-2 Update the package project wapproj file for the version your using
-<pre> < Content Include="FixedRuntime\95.0.1020.53\\**\*.*" > </pre>
-3 Uncomment the code in app.xaml.cs to enable the runtime override
-<pre>
-public App()
-{
-    this.InitializeComponent();
-    // If you are shipping a fixed version WebView2 SDK with your application you will need
-    // to use the following code (update the runtime version to what you are shipping.
-    StorageFolder localFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;
-    String fixedPath = Path.Combine(localFolder.Path, "FixedRuntime\\95.0.1020.53");
-    Debug.WriteLine($"Launch path [{localFolder.Path}]");
-    Debug.WriteLine($"FixedRuntime path [{fixedPath}]");
-    Environment.SetEnvironmentVariable("WEBVIEW2_BROWSER_EXECUTABLE_FOLDER", fixedPath);

+# WinUI 3 (Windows App SDK) sample app
 
+This sample (**WebView2_WinUI3_Sample**) demonstrates using a WebView2 control in a WinUI 3 (Windows App SDK) Packaged application.
 
+![Sample app](./images/sample-app.png)
 
+This sample also allows you to ship the app with a fixed-version WebView2 Runtime, instead of using whichever version of the WebView2 Runtime is installed and running on the user's computer.
 
+To use this sample, see [WinUI 3 (Windows App SDK) sample app](https://learn.microsoft.com/microsoft-edge/webview2/samples/webview2-winui3-sample).
