Merge pull request #3697 from grpc/release-0_11

release-0_11 -> master integration

examples/python/README.md

+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
+  ```
+
