+> Paket enabled us to share code between repositories and solutions without the need to create new packages every time something changed.
+
+[Rhein-Spree](https://www.rhein-spree.com) is software services and consulting company from Berlin with teammates in Leipzig, Dresden and Düsseldorf. We are focused on .NET Technologies with great results.
+
+When it comes to dependency management in growing environment with multiple solutions etc. we
+felt the pain of inconsistent resolution of package versions across the repository. It got
+even harder as the solutions grew. At some point we decided to give Paket a try and what should
+we say... We had some work in getting the dependencies file correct and then it worked like a
+charm. Even better. We also started to use the git functionality of Paket in referencing other
+git repositories. This enabled us to share code between repositories and solutions without the
+need to create new packages everytime something changed.
+
+So the time we needed to resolves versioning issues has decreased tremendously. 
+
+Great work, please keep it up!
