 You can use the following script to install Docker and start a 4-node PBFT cluster in one instruction.
 
 ```sh
 $ bash setupPbft.sh
 ```
 
+tldr :)

 ## Preparation
 
 ### Download Images
 
 *The latest code is evolving quickly, we recommend to use the 0.6 branch code currently.*
 
-Pull necessary images of peer, base image and the membersrvc.
+Pull necessary images of peer, base image and the membersrvc. You can use any one from below options
+
+#### Option 1: Use our images
+
+We maintained a tested dockerhub image with latest changes.
 
 ```sh
-$ docker pull yeasy/hyperledger-fabric:0.6-dp
-$ docker tag yeasy/hyperledger-fabric:0.6-dp hyperledger/fabric-peer:latest
-$ docker tag yeasy/hyperledger-fabric:0.6-dp hyperledger/fabric-baseimage:latest
-$ docker tag yeasy/hyperledger-fabric:0.6-dp hyperledger/fabric-membersrvc:latest

+  && docker tag yeasy/hyperledger-fabric:0.6-dp hyperledger/fabric-membersrvc
 ```
 
+#### Option 2: Use community images
 The community [images](https://hub.docker.com/r/hyperledger/) are also available at dockerhub, use at your own choice.
 
+```bash
+$ docker pull hyperledger/fabric-peer:x86_64-0.6.1-preview \
+  && docker pull hyperledger/fabric-membersrvc:x86_64-0.6.1-preview \

+  && docker tag hyperledger/fabric-membersrvc:x86_64-0.6.1-preview hyperledger/fabric-membersrvc
+```
+
+#### Option 3: Use IBM certificated images
+IBM also provides some tested [images](http://www-31.ibm.com/ibm/cn/blockchain/index.html), available at [dockerhub](http://www-31.ibm.com/ibm/cn/blockchain/index.html), use at your own choice.
