+#### Multiple Screens
+
+Blessed supports the ability to create multiple screens. This may not seem
+useful at first, but if you're writing a program that serves terminal
+interfaces over http, telnet, or any other protocol, this can be very useful.
+
+##### Server Side Usage
+
+A simple telnet server might look like this (see examples/blessed-telnet.js for
+a full example):
+
+``` js
+var blessed = require('blessed');
+var telnet = require('telnet2');
+
+telnet({ tty: true }, function(client) {
+  client.on('term', function(terminal) {
+    screen.terminal = terminal;
+    screen.render();
+  });
+
+  client.on('size', function(width, height) {
+    client.columns = width;
+    client.rows = height;
+    client.emit('resize');
+  });
+
+  var screen = blessed.screen({
+    smartCSR: true,
+    input: client,
+    output: client,
+    terminal: 'xterm-256color',
+    fullUnicode: true
+  });
+
+  client.on('close', function() {
+    if (!screen.destroyed) {
+      screen.destroy();
+    }
+  });
+
+  screen.key(['C-c', 'q'], function(ch, key) {
+    screen.destroy();
+  });
+
+  screen.on('destroy', function() {
+    if (client.writable) {
+      client.destroy();
+    }
+  });
+
+  screen.data.main = blessed.box({
+    parent: screen,
+    left: 'center',
+    top: 'center',
+    width: '80%',
+    height: '90%',
+    border: 'line',
+    content: 'Welcome to my server. Here is your own private session.'
+  });
+
+  screen.render();
+}).listen(2300);
+```
+
+Once you've written something similar and started it, you can simply telnet
+into your blessed app:
+
+``` bash
+$ telnet localhost 2300
+```
+
+Creating a netcat server would also work as long as you disable line buffering
+and terminal echo on the commandline via `stty`:
+`$ stty -icanon -echo; ncat localhost 2300; stty icanon echo`
+
+Or by using netcat's `-t` option: `$ ncat -t localhost 2300`
+
+Creating a streaming http 1.1 server than runs in the terminal is possible by
+curling it with special arguments: `$ curl -sSNT. localhost:8080`.
+
+There are currently no examples of netcat/nc/ncat or http->curl servers yet.
+
+---
+
+The `blessed.screen` constructor can accept `input`, `output`, and `term`
+arguments to aid with this. The multiple screens will be managed internally by
+blessed. The programmer just has to keep track of the references, however, to
+avoid ambiguity, it's possible to explicitly dictate which screen a node is
+part of by using the `screen` option when creating an element.
+
+The `screen.destroy()` method is also crucial: this will clean up all event
+listeners the screen has bound and make sure it stops listening on the event
+loop. Make absolutely certain to remember to clean up your screens once you're
+done with them.
+
+A tricky part is making sure to include the ability for the client to send the
+TERM which is reset on the serverside, and the terminal size, which is should
+also be reset on the serverside. Both of these capabilities are demonstrated
+above.
+
+For a working example of a blessed telnet server, see
+`examples/blessed-telnet.js`.
