-## 3.1 S5afs, S5 All Flash System
+## 3.1 pfs, S5 All Flash System
   This module is the server daemon, provide all data service on store. include:
    1) SSD disk management
    2) Networ interface (RDMA and TCP protocol)
    3) IO handling
 
   There're at most 1024 S5afs nodes in a cluster. All s5afs works in acitve mode, since every s5afs need to provide data service.
 
-## 3.2 S5conductor
+## 3.2 pfconductor
   This is the control module to conduct all players in storage cluster. A cluster should has at least 2 s5conductor nodes and at most 5 are supported.
-  S5conductor works in active-standby mode. only one conductor is active. All others in standby.
+  pfconductor works in active-standby mode. only one conductor is active. All others in standby.
+  This module is programed in Java and reside in repository: https://github.com/cocalele/pfconductor
 
 ## 3.3 Zookeeper
   All conductor and afs nodes(instance) register themself to zookeeper, so the active conductor can discovery services in cluster.
 
 ## 3.4 MetaDB
   MetaDB is a MariaDB cluster with HA.   
 
-## 3.5 S5bd and S5kd
-  S5bd is user space client. Qemu   
+## 3.5 pfbd 
+  pfbd is user space client. also a virtio-block Qemu driver is provided in https://github.com/cocalele/qemu/tree/pfbd

+使用docker快速搭建开发环境
+============================
+
+1. pull docker image
+
+```
+# docker pull pureflash/pfs-dev:1.6
+```
+
+如果这个镜像拉取失败，可以从百度网盘下载：https://pan.baidu.com/s/1nGYIpP-WFOUXxv3vfQwPxQ?pwd=4564
+然后导入：
+```
+# gunzip pfs-dev.tar.gz
+# docker load < pfs-dev.tar
+```
+
+2. check out code
+```
+  # mkdir ~/pf && cd ~/pf
+  # git clone https://gitee.com/cocalele/PureFlash.git
+  # set PFHOME=$(pwd)/PureFlash
+  # cd PureFlash
+  # git submodule init
+  # git submodule update
+  # cd .. #to pf again
+  # git https://gitee.com/cocalele/jconductor.git
+```  
+
+3. run docker
+```
+  # docker run -ti  --ulimit core=-1 --privileged --hostname pfs-d  --net pfnet --ip 172.1.1.2  --rm -v ~/pf:/root/pf   --name pfs-d  -e TZ=Asia/Shanghai pureflash/pfs-dev:1.6 /bin/bash
+```
+  上面命令里的-v ~/pf:/root/pf  把刚才的源代码目录mount到了容器里面的/root/pf目录上。然后就可以参照build_and_run.txt文档里面的cmake, ant步骤分别编译PureFlash和jconductor
+
