const info = network.info(key)

// high level automated:

network.join(key, {
  announce: true, // announce self and listen for connections
  lookup: true // seek out peers and connect to them
})
network.leave(key)

network.on('connection', function (socket) {
})

// more manual:

var lookup = network.disc.lookup(key)
network.disc.lookupOne(key, function (peer) {
  network.connect(peer, function (socket) {
  })
})
