 A curses-like library for node.js.
 
+As of right now, it does not read all terminfo. It was designed for one
+terminal's terminfo: **xterm**.
+
+I want this library to eventually become a high-level library for terminal
+widgets.
+
+## Example Usage
+
+``` js
+var Program = require('blessed').Program
+  , program = new Program;
+
+program.on('key', function(ch, key) {
+  if (key.ctrl && key.name === 'c') {
+    console.log('This would have been SIGINT!');
+  }
+});
+
+program.setMouse({ normalMouse: true });
+
+program.mouse('mouse', function(data) {
+  console.log('Mouse event received:');
+  console.log(data.button, data.x, data.y);
+});
+
+program.alternateBuffer();
+
+program.clear();
+
+program.bg('white');
+program.fg('blue');
+program.write('Hello world');
+program.fg('!blue');
+program.setx(1);
+program.down(5);
+program.write('Hi again!');
+program.bg('!white');
+program.feed();
+
+program.getCursor(function(data) {
+  console.log('Cursor is at: %s, %s.', data.x, data.y);
+
+  program.charset('SCLD');
+  program.write('abcdefghijklmnopqrstuvwxyz0123456789');
+  program.charset('US');
+  program.setx(0);
+
+  setTimeout(function() {
+    program.eraseInLine('right');
+    setTimeout(function() {
+      program.clear();
+      program.normalBuffer();
+      program.setMouse({ normalMouse: false });
+    }, 2000);
+  }, 2000);
+});
+```
