 ## Start a network base on kafka
 
 ```bash
-$ docker-compose -f orderer-kafka.yaml up
+$ cd ~/docker-compose-files/tree/master/hyperledger/1.0/kafka
+$ docker-compose -f orderer-kafka.yaml up (-d)
 ```
+When the fabric-network fully started, it takes about 15-20s. 
 
-### Chaincode
+## Test chaincode
 
 ```bash
 $ docker exec -it fabric-cli bash
-$ bash ./scripts/initialize.sh
+$ bash ./scripts/initialize.sh # initialize the fabric network
 $ bash ./scripts/test_4peers.sh
 ```
+
+>(Optional) If you want to use official images, you can run the following command first
+>
+> ```bash
+> $ cd ~/docker-compose-files/tree/master/hyperledger/1.0
