-# SystemJS
+# Workbox
 
-SystemJS is intended to be a JavaScript based web runtime environment. 
-It will provide a UI framework, Window Manager, Console, Virtual Filesystem and more.
+Workbox is a desktop environment (simulator?) in your web browser.
+Currently it can't do a lot and is mostly very alpha.
 
-I will add more details soon.
+But it's build with web workers, so that's cool.
