 and the other to be `10.1.1.2`. Make sure to update the interface's IP
 address for the machine who needs to change to be `10.1.1.2`.
 
-### Update our Discover Key
-
-Looking in the interface's configuration you'll also notice a field called
-`discover_key` (right above the interface's private key). It doesn't matter
-which discovery key you pick but it much be the same for all of the nodes in your little cluster
-so that they can find each other.
-
-(*Note you can use different `discover_key`s with different interfaces on the same 
-host to create different isolated networks.)
-
-```yaml
-discover_key: fiftieth-dandelion-wronged-craftwork
-```

 ### Starting Up the Interfaces!
 Now that we've got our configs all sorted we can start up the two interfaces!
