-Route Server Scenario Test
+Scenario Test
========================
-Preparation
------------
-Please set up Ubuntu 14.04 Server Edition virtual machine,
-and install golang environment inside the VM.
+This page explains how to set up a scenario test environment and run the test.
-Setup
------
-Execute the following commands inside the VM:
+## Prerequisites
+
+Assume you finished setting up [Golang](https://golang.org/doc/install) and [Docker](https://docs.docker.com/installation/ubuntulinux/) on Ubuntu 14.04 Server VM.
+We recommend allocating memory more than 8GB to the VM.
+Because this scenario test runs a lot of test cases concurrently.
+
+## Check
+Please check if Golang and Docker is installed correctly and
+make sure the $GOPATH is defined.
-- ##### 1. Install and setting the packages required to run the scenario test.
```shell
-$ sudo apt-get update
-$ sudo apt-get install git python-pip python-dev iputils-arping bridge-utils lv
-$ sudo wget https://raw.github.com/jpetazzo/pipework/master/pipework -O /usr/local/bin/pipework
-$ sudo chmod 755 /usr/local/bin/pipework
-$ sudo apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
-$ sudo apt-get install docker-engine
-$ gpasswd -a `whoami` docker
+$ go version
+go version go1.5.1 linux/amd64
+
+$ echo $GOPATH
+/home/yokoi-h/work
+
+$ sudo docker version

```
+
+## Set up dependencies
+Execute the following commands inside the VM to install the dependencies:
+
+1. Install pip and [pipework](https://github.com/jpetazzo/pipework).
+
+ ```shell
+ $ sudo apt-get update
+ $ sudo apt-get install git python-pip python-dev iputils-arping bridge-utils lv
+ $ sudo wget https://raw.github.com/jpetazzo/pipework/master/pipework -O /usr/local/bin/pipework
+ $ sudo chmod 755 /usr/local/bin/pipework
+ ```
+
+
+1. Get docker images.
+ Download docker images pertaining to GoBGP testing.
+
+ ```shell
+ $ sudo docker pull golang:1.5
+ $ sudo docker pull osrg/quagga
+ $ sudo docker pull osrg/gobgp
+ ```
+
+
+1. Clone gobgp and install python libraries.
+
+ ```shell
+ $ mkdir -p $GOPATH/src/github.com/osrg
+ $ cd $GOPATH/src/github.com/osrg
+ $ git clone https://github.com/osrg/gobgp.git
+ $ cd ./gobgp/test/scenario_test
+ $ sudo pip install -r pip-requires.txt
+ ```
-- ##### 2. Get each docker image from Docker Hub.
-```shell
-$ sudo docker pull osrg/golang:1.5
-$ sudo docker pull osrg/quagga
-$ sudo docker pull osrg/gobgp
+## Install local source code
+You need to install local source code into gobgp docker container.
+You also need this operation at every modification to the source code.
+
```

-
-- ##### 3. Download gobgp and install python libraries.
-```shell
-$ git clone https://github.com/osrg/gobgp.git
-$ cd ./gobgp
-$ GOBGP_DIR=`pwd`
-$ cd ${GOBGP_DIR}/test/scenario_test
-$ pip install -r pip-requires.txt
-```

-Start
------
-##### All scenario test
-You can run the all scenario test in the following shell script.
-```shell
-./run_all_tests.sh [
