+gRPC in 3 minutes (Python)
+========================
+
+Background
+-------------
+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
+-------
+  ```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
+  $ # Clone the repository to get the example code:
+  $ git clone https://github.com/grpc/grpc
+  $ # Navigate to the "hello, world" Python example:
+  $ cd grpc/examples/python/helloworld
+  ```
+
+Try it!
+-------
+
+- Run the server
+
+  ```sh
+  $ python2.7 greeter_server.py &
+  ```
+
+- Run the client
+
+  ```sh
+  $ python2.7 greeter_client.py
+  ```
+
+Tutorial
+--------
+
+You can find a more detailed tutorial in [gRPC Basics: Python][]

+[helloworld.proto]:../protos/helloworld.proto

 ## PREREQUISITES
 - `node`: This requires `node` to be installed. If you instead have the `nodejs` executable on Debian, you should install the [`nodejs-legacy`](https://packages.debian.org/sid/nodejs-legacy) package.
-- [homebrew][] on Mac OS X.  These simplify the installation of the gRPC C core.
 
 ## INSTALLATION
 
-**Linux (Debian):**
-
-Add [Debian jessie-backports][] to your `sources.list` file. Example:
-
-```sh
-echo "deb http://http.debian.net/debian jessie-backports main" | \
-sudo tee -a /etc/apt/sources.list
-```
-
-Install the gRPC Debian package
-
-```sh
-sudo apt-get update
-sudo apt-get install libgrpc-dev
-```
-
 Install the gRPC NPM package
 
 ```sh
 npm install grpc
 ```
 
-**Mac OS X**
-
-Install [homebrew][]. Run the following command to install gRPC Node.js.
-```sh
-$ curl -fsSL https://goo.gl/getgrpc | bash -s nodejs
-```
-This will download and run the [gRPC install script][], then install the latest version of gRPC Nodejs npm package.
-
 ## BUILD FROM SOURCE
  1. Clone [the grpc Git Repository](https://github.com/grpc/grpc).
- 2. Follow the instructions in the `INSTALL` file in the root of that repository to install the C core library that this package depends on.
  3. Run `npm install`.
 
-If you install the gRPC C core library in a custom location, then you need to set some environment variables to install this library. The command will look like this:
-
-```sh
-CXXFLAGS=-I<custom location>/include LDFLAGS=-L<custom location>/lib npm install [grpc]
-```
-
 ## TESTING
 To run the test suite, simply run `npm test` in the install location.

-The command line tool `bin/service_packager`, when called with the following command line:
-
-```bash
-service_packager proto_file -o output_path -n name -v version [-i input_path...]
-```
-
-Populates `output_path` with a node package consisting of a `package.json` populated with `name` and `version`, an `index.js`, a `LICENSE` file copied from gRPC, and a `service.json`, which is compiled from `proto_file` and the given `input_path`s. `require('output_path')` returns an object that is equivalent to
