port forarding doesn't correct described in readme

[mogol07]

Hi!

in readme said

Forward the cluster port locally since it's not exposed to the Internet by default. Do this every time you want to interact with the cluster: ./ssh-node gateway

but this command open new terminal session, not just forwarding port.
To achive only port forwarding, I need to use
./ssh-node gateway -fN

i.e. no run command, only forward port. But to finish process I need to kill process.
Maybe make sense to update readme?

Hi @mogol07, Thank you for your feedback. Yes, you're right, the command will also open a shell. Would you create a PR to update the documentation accordingly? I'm not sure how useful it is to just get the port forwarded without a shell on the host but feel free to point out this option.
