+Are you in the right place?
+------------------------
+
+Dear Node.js Users:
+
+You SHOULD NOT use this module. You already have [`Buffer`](https://nodejs.org/api/buffer.html) and [`thirty-two`](https://github.com/chrisumbel/thirty-two):
+
+```javascript
+var buf = new Buffer('I ½ ♥ 💩', 'utf8');
+buf.toString('hex');
+buf.toString('base64');
+buf.toString('ascii');
+buf.toString('utf8');
+buf.toString('binary'); // deprecated, do not use
+```
+
+Install
+-------
+
+You just include the `index.js` in a lovely script tag.
+
+```bash
+bower install --save unibabel
+```
+
+```html
+<script src="/bower_components/unibabel/index.js"></script>
+```
+
+Dear WebPack / Broccoli, Gulp / Grunt Users:
+
+I don't know how your build systems work these days,
+but Unibabel is exported as `Unibabel`
+and you can access it as `window.Unibabel`.
