 A note about running Umbraco from Visual Studio.

-When upgrading your website using nuget a backup of config files and web.config will be created and the files will
-be overwritten with those from the current release. This means that you'll have to merge the files if you made any
-changes to the previous config files.
+When upgrading your website using nuget a backup of config files and web.config will be created. Only the web.config will
+be overwritten by default to ensure that it has the necessary settings from the current release. This means that you'll 
+have to merge the files if you made any changes to the previous config files.
+The config files found in the config folder will usually not be changed for patch releases, so they can usually be skipped,
+but the web.config will have to have its previous "umbracoConfigurationStatus"-appsetting and "umbracoDbDSN" connection string
+copied over (as a minimum).

-It's not possible to create a deploy package from Visual Studio, which contains everything out of the box. This is
-due to a number of files and folders that are not added to the Visual Studio project. These folders include:
-install, umbraco and umbraco_client.
-A custom deploy script will be added in a later release.
+This nuget package includes build targets that extends 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.
+These folders will now be automatically included when creating a deploy package or publishing to the file system:
+umbraco and umbraco_client.

-Please read the release notes on Codeplex:
-http://umbraco.codeplex.com/releases
