-A note about running Umbraco from Visual Studio.
-
 Don't forget to build!

 When upgrading your website using NuGet you should answer "No" to the questions to overwrite the Web.config 
 file (and config files in the config folder). 

-We've done our best to transform your configuration files but in case something is not quite right: remember we
-backed up your files in App_Data\NuGetBackup so you can find the original files before they were transformed.
-
-We've overwritten all the files in the Umbraco and Umbraco_Client folder, these have been backed up in 
-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 
-sure to do a compare and merge with the NuGetBackup folder.
-
 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.
