+#Notes for this Repository
+This is a fork of the original Validation from Intertech: [Intertech/aa-validation-from-server](https://github.com/IntertechInc/aa-validation-from-server)
+
+The fork was done for following reasons:
+
+* Use a JSON serializer rather than creating the JSON string by hand. This results in easier extensibility.
+* Support for hierararchical viewmodels
+* Configurable and extendable creation of the errormessages
+
+You can watch the state of the integration in the parent project here:
+[Issue 11](https://github.com/IntertechInc/aa-validation-from-server/issues/11)
+
+To build this NuGet Package see [development.md](development.md).
