+tools to build and run.
+
+For this sample, we've already generated the server and client stubs from [helloworld.proto][].
+
+Example projects in this directory depend on the [Grpc](https://www.nuget.org/packages/Grpc/)
+and [Google.Protobuf](https://www.nuget.org/packages/Google.Protobuf/) NuGet packages
+which have been already added to the project for you.
+
+The examples in this directory target .NET 4.5 framework, as .NET Core support is
+currently experimental.
+
+PREREQUISITES
+-------------
+
+- The DotNetCore SDK cli.
+
+- The .NET 4.5 framework.
+
+Both are available to download at https://www.microsoft.com/net/download
+
+BUILD
+-------
+
+From the `examples/csharp/helloworld-from-cli` directory:
+
+- `dotnet restore`
+
+- `dotnet build **/project.json` (this will automatically download NuGet dependencies)
+
+Try it!
+-------
+
+- Run the server
+
+  ```
+  > cd GreeterServer
+  > dotnet run
+  ```
+
+- Run the client
+
+  ```
+  > cd GreeterClient
+  > dotnet run
+  ```
