+## Disabling Implicit Uno Packages
+
+If you wish to disable Implicit package usage, add the following:
+
+```xml
+<DisableImplicitUnoPackages>true</DisableImplicitUnoPackages>
+```
+
+to your `Directory.Build.props` file or `csproj` file. You will be then able to manually add the NuGet packages for your project.
 
 > [!NOTE]
 > When disabling Implicit Uno Packages it is recommended that you use the `$(UnoVersion)` to set the version of the core Uno packages that are versioned with the SDK as the SDK requires `Uno.WinUI` to be the same version as the SDK to ensure proper compatibility.
