**Description of the issue:**

Currently it correctly states that you need a second node running, but from what I am understanding with federation and the two node example is that both nodes need to have a cert issued by the same CA, otherwise they will not be able to validate each other. However, if to set up the second node a user was to go through the single node example again, it would regenerate a separate CA for the second node which would lead to each node not being able to validate each other's cert.

I think these leads to a case where federation in general needs more doc in order to explain just how nodes are trusting each other.
