 According to some preliminary `benchmarks <https://github.com/cart/godot3-bunnymark>`_, performance of C# in Godot - while generally in the same order of magnitude - is roughly **~4x** that of GDScript in some naive cases.
 For full performance, C++ is still a little faster; the specifics are going to vary according to your use case. GDScript is likely fast enough for most general scripting workloads.
 C# is faster, but requires some expensive marshalling when talking to Godot.

+Using Nuget Packages in Godot
+-----------------------------
+
+`Nuget <https://www.nuget.org/>`_ Packages can be installed and used with Godot,
+as with any project. Many IDEs (such as vs code) can add packages directly. They
+can also be added manually by adding the package reference in the .csproj file
+located in the project root:
+
+      <ItemGroup>
+        <PackageReference Include="Newtonsoft.Json" Version="11.0.2"/>
+      </ItemGroup>
+      ...
+    </Project>
+
+
+Then using the dotnet command line to restore package, in the project root:
