 This configuration specifies 2 networks (chains), `ibc-0` and `ibc-1`. A typical workflow might look like:
 
 ```bash
+# Start the two chains
+$ gm start
+
 # Generate the config for `hermes`. 
 # Notably, this will create the appropriate `[[chains]]` entries for `ibc-0` and `ibc-1`.
 $ gm hermes config
 
 # Generate the keys so that `hermes` can sign transactions on both chains
 $ gm hermes keys
 
-# Start the two chains
-$ gm start

 # Create a connection 
-$ hermes create connection ibc-0 ibc-1
+$ hermes create connection --a-chain ibc-0 --b-chain ibc-1
