+
+Warning: very incomplete and extremely experimental, mostly nothing works
+
+Usage:
+
+    npm install
+    npm start
+
+Navigate to the URL in your web browser, and open the developer console.
+The APIs for [browserify](https://github.com/substack/node-browserify)
+and [npm](https://github.com/npm/npm) are available in the global
+`browserify` and `npm` objects, respectively. For example, you can run:
+
+    npm.commands.version()
+    npm.commands.substack()
+    npm.commands.xmas()
+
+Requires a browser implementing the [Filesystem API](http://www.html5rocks.com/en/tutorials/file/filesystem/)
+(tested on Chrome version 40).
