 Angular.dart's Todo Demo
 ========================
 
 This demo is the most complete demo in the repository and a great
 starting point for quickly understanding Angular.dart
 
 Getting up and running
 ----------------------
 
 To run this demo, first clone the entire Angular.dart repository.
 
-Then, run `pub serve` in this directory:

 The server is optional
 ----------------------
 
 There is a simple Node.js server in this directory, but you do
 not need to run it.  It is here to demonstrate the HTTP record /
 playback feature, snapshotting and dart2js.
 
 ```
-$ cd example
-$ node webserver.js
+$ cd demo/todo; node webserver.js
 Web server is listening on port 3000
 ```
