-## Goal
+[!CAUTION]
+> Only modify the source code if you standard platform customization capabilities.
+> Manual changes might make the source source code invalid but still importable to Dataverse.
+> In some situations, this could cause your environment to become irreversibly corrupted.
 
+## Goal
 The primary objective of this NuGet package is to help Power Platform developers customize the MSBuild process (dotnet build) for their Dataverse solution components. Customizations are done using a set of build tasks which make development workflows more productive and automated.
