Documentation and examples

I'm looking at cfssl and using it to deliver a secure etcd cluster. I've been able, through much experimentation, to find the right combo of stuff to create certificates for peers. However, if I try to connect to a single etcd node with etcdctl, I need that node's cert, key, and the CA cert.

This is unworkable and won't scale for our application using etcd which will have to use these three files.

mkbundle is mentioned in the README here and my hope is that it will combine all the certs and keys plus the CA and create a single PEM file that can be used from anywhere to access any node in the cluster.

There's an example in the README and it seems straightforward. Is that all there is to it?
