-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.
-
-
-Install gRPC:
-```sh
-  $ pip install grpcio
-```
-Or, to install it system wide:
-```sh
-  $ sudo pip install grpcio
-```
-
-If you're on Windows, make sure you installed the `pip.exe` component when you
-installed Python. Invoke as above but with `pip.exe` instead of `pip` (you may
-also need to invoke from a `cmd.exe` ran as administrator):
-```sh
-  $ pip.exe 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:
-  $ 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
-  ```
-
