 These examples will use a single node cluster to show you the basics of the etcd REST API. Lets start etcd:
 
 ```sh
-./etcd -d node0
+./etcd -d node0 -n node0
 ```
 
-This will bring up an etcd node listening on port 4001 for client communication and on port 7001 for server-to-server communication. The `-d node0` argument tells etcd to write node configuration, logs and snapshots to the `./node0/` directory.
