 This page explains how to managing GoBGP with your favorite Language.
 You can use any language supported by [gRPC](http://www.grpc.io/) (10
 languages are supported now). This page gives an example in Python,
-Ruby, C++, Node.js, and Java. It assumes that you use Ubuntu 14.04 (64bit).

-We need to install ProtocolBuffers and gRPC libraries.
-
-### Install ProtocolBuffers:
-```bash
-$ sudo apt-get update
-$ sudo apt-get install -y build-essential autoconf git libtool unzip
-$ mkdir ~/work
-$ cd ~/work
-$ wget https://github.com/google/protobuf/archive/v3.0.0-beta-1.tar.gz
-$ tar xvzf v3.0.0-beta-1.tar.gz
-$ cd protobuf-3.0.0-beta-1
-$ ./autogen.sh
-$ ./configure
-$ make
-$ sudo make install
-$ vi ~/.bashrc
-  export LD_LIBRARY_PATH=/usr/local/lib
-```
-
-please check the version.
- ```bash
- $ protoc --version
- libprotoc 3.0.0
- ```
+## <a name="prerequisite"> Prerequisite
+We assumes that you have finished installing `protoc` [protocol buffer](https://github.com/google/protobuf) compiler to generate stub server and client code and "protobuf runtime" for your favorite language.
 
-### Install gRPC:
-```bash
-$ sudo apt-get update
-$ sudo apt-get install -y python-all-dev python-virtualenv
-$ cd ~/work
-$ git clone https://github.com/grpc/grpc.git
-$ cd grpc
-$ git checkout -b release-0_11_1 release-0_11_1
-$ git submodule update --init
-$ make
-$ sudo make install
-```
+Please refer to [the official docs of gRPC](http://www.grpc.io/docs/) for details.
 
-### Install Python Libraries:
-
-Install python libraries for protobuf and gRPC.
-Please use virtualenv if you want to keep your environment clean.
-In this example we create venv directory at $HOME/venv.
-
-```bash
-$ virtualenv ~/venv
-$ source ~/venv/bin/activate
-$ cd ~/work/protobuf-3.0.0-beta-1/python
-$ python setup.py install
-$ cd ~/work/grpc/src/python/grpcio/
-$ python setup.py install
-$ deactivate

-### Install Protocol Buffers:
-
-Install protobuf v3.0.0-beta before gRPC. gRPC installation process will try to do it automatically but fail. (Probably because it tries another version of protobuf)
