-App_Data\NuGetBackup. We didn't overwrite the UI.xml file nor did we remove any files or folders that you or
-a package might have added. Only the existing files were overwritten. If you customized anything then make

 This NuGet package includes build targets that extend the creation of a deploy package, which is generated by
 Publishing from Visual Studio. The targets will only work once Publishing is configured, so if you don't use
 Publish this won't affect you.
+
 The following items will now be automatically included when creating a deploy package or publishing to the file
 system: umbraco, config\splashes and global.asax.
