[erlang-questions] How to dynamically add one node to erlang's distrubted application?

[devdoer bird]

HI:
I have a distrbuted system  using erlang's distributed application
mechanism.It firstly ran on 3 nodes with the config file like this:

[{kernel,
  [{distributed, [{myapp, 5000, [cp1@REDACTED, {cp2@REDACTED, cp3@REDACTED}]}]},
   {sync_nodes_mandatory, [cp2@REDACTED, cp3@REDACTED]},
   {sync_nodes_timeout, 5000}
  ]
}
].

Now I want to  add one more node to  the system  .How can I do this using
erlang's distributed applicaiton mechanism? Do I have to edit the config
file on all 3 nodes to add the 4th node and restart all of them?

Thanks .
