 For this sample, we've already generated the server and client stubs from
 [helloworld.proto][] and we'll be using a specific reference platform.
 
-Prerequisites
--------------
-
-- Debian 8.2 "Jessie" platform with `root` access
-- `git`
-- `python2.7`
-- `pip`
-- Python development headers
 
-Set-up
--------
+Install gRPC:
   ```sh
-  $ # install the gRPC Core:
-  $ sudo apt-get install libgrpc-dev
-  $ # install gRPC Python:
-  $ sudo pip install -U grpcio==0.11.0b1
-  $ # Since this "hello, world" example uses protocol buffers:
-  $ sudo pip install -U protobuf==3.0.0a3
+  $ pip install grpcio
+```
+Or, to install it system wide:
+```sh
+	$ sudo pip install grpcio
+```
+
+Download the example
+```sh
   $ # Clone the repository to get the example code:
   $ git clone https://github.com/grpc/grpc
   $ # Navigate to the "hello, world" Python example:

-TROUBLESHOOTING
+THE NATIVE DEPENDENCY
 ---------------
 
-### Problem: Unable to load DLL 'grpc_csharp_ext.dll'
-
-Internally, gRPC C# uses a native library written in C (gRPC C core) and invokes its functionality via P/Invoke. `grpc_csharp_ext` library is a native extension library that facilitates this by wrapping some C core API into a form that's more digestible for P/Invoke. If you get the above error, it means that the native dependencies could not be located by the C# runtime (or they are incompatible with the current runtime, so they could not be loaded). The solution to this is environment specific.
-
-- If you are developing on Windows in Visual Studio, the `grpc_csharp_ext.dll` that is shipped by gRPC nuget packages should be automatically copied to your build destination folder once you build. By adjusting project properties in your VS project file, you can influence which exact configuration of `grpc_csharp_ext.dll` will be used (based on VS version, bitness, debug/release configuration).
-
-- If you are running your application that is using gRPC on Windows machine that doesn't have Visual Studio installed, you might need to install [Visual C++ 2013 redistributable](https://www.microsoft.com/en-us/download/details.aspx?id=40784) that contains some system .dll libraries that `grpc_csharp_ext.dll` depends on (see #905 for more details).
-
-- On Linux (or Docker), you need to first install gRPC C core and `libgrpc_csharp_ext.so` shared libraries.
-  See [How to Use](#how-to-use) section for details how to install it.
-  Installation on a machine where your application is going to be deployed is no different.
-
-- On Mac, you need to first install gRPC C core and `libgrpc_csharp_ext.dylib` shared libraries using Homebrew. See above for installation instruction.
-  Installation on a machine where your application is going to be deployed is no different.
+Internally, gRPC C# uses a native library written in C (gRPC C core) and invokes its functionality via P/Invoke. `grpc_csharp_ext` library is a native extension library that facilitates this by wrapping some C core API into a form that's more digestible for P/Invoke.
 
-- Possible cause for the problem is that the `grpc_csharp_ext` library is installed, but it has different bitness (32/64bit) than your C# runtime (in case you are using mono) or C# application.
+Prior to version 0.13, installing `grpc_csharp_ext` was required to make gRPC work on Linux and MacOS. Starting with version 0.13, we have improved the packaging story significantly and precompiled versions of the native library for all supported platforms are now shipped with the NuGet package. Just installing the `Grpc` NuGet package should be the only step needed to use gRPC C#, regardless of your platform (Windows, Linux or Mac) and the bitness (32 or 64bit).
