 ## Installation
 
-Currently Express must be cloned (or downloaded), you can use the following command to
-get rolling and initialize the submodule dependencies:
-
-    $ git clone git://github.com/visionmedia/express.git && cd express && git submodule update --init && make app
-    
-Or with the [gh](http://github.com/visionmedia/gh) utility:
-
-    $ gh clone visionmedia express && cd express && git submodule update --init && make app
-
-## Performance
-
-  Extensive benchmarking will wait until a development version
-  has been released. 
+  Install the [Kiwi package manager for nodejs](http://github.com/visionmedia/kiwi)
+  and run:
   
-  Currently Express can chew through a request with a two Haml views (*page and layout*) 
-  requested **2000** times with concurrency of **80** in **2.4** seconds and **814**
-  requests per second. With no caching involved.
+      $ kiwi install express
+      
+or
+
+  Install via git clone:
   
-  An identical Sinatra application was served with the **Thin** HTTP server
-  and scored **8.3** seconds and **238** requests per second. In this situation
-  Express is currently **3.5** times faster than Sinatra.
+      $ git clone git://github.com/visionmedia/express.git && cd express && git submodule update --init
 
 ## Examples
 
-Below is a minimal app example when express is already within your load path.

 framework to write and run elegant spec suites. JSpec is frozen
