 This is the recommended way to start an IoTeX node
 
 1. Pull the docker image:
 
 ```
-docker pull iotex/iotex-core:v0.10.2
+docker pull iotex/iotex-core:v0.10.3
 ```

 3. Edit `$IOTEX_HOME/etc/config.yaml`, look for `externalHost` and `producerPrivKey`, uncomment the lines and fill in your external IP and private key. You also need to replace the `gravityChainAPIs` to use your own infura project key. And make sure you enabled archive data access if you need to access Ethereum archive node data.
