 # Running Mojo Applications
 
 A Mojo application written in JavaScript is launched with mojo_shell like this:
 
 ```
   mojo_shell <js-application-url>
 ```
 
 Where js-application-url is a URL understood by the shell. For example
 a file or an http URL that names a JS source file. The JS file itself

 service's Mojo interface. The bindings are generated by the build system and end
 up in files whose name is the same as the '.mojom' file with a '.js'
 suffix. It's often helpful to look at the generated '.mojom.js' files.
 
 The JS bindings for a Mojo interface's API are delivered as a JS module whose
 name is based on the '.mojom' file's path. For example, to use the Mojo network
 service you need the JS module based on network_service.mojom:
 
 ```javascript
   define("main", [
-    "mojo/services/network/public/interfaces/network_service.mojom",
+    "mojo/services/network/interfaces/network_service.mojom",
     "mojo/services/public/js/application",
   ]
     function(net, application) {
       class MyApplication extends application.Application {
         initialize(args) {
           var netService = this.shell.connectToService(
               "mojo:network_service", net.NetworkService);
           // Use netService's NetworkService methods.

 The JS Shell class simplifies connecting to applications and services. It's a
 wrapper for the Application's appShell argument. The Application constructor
 creates a Shell and assigns it to `this.shell`.
 
 The Shell's connectToService() method returns a "proxy" to a service provided by
 another application.
 
 ```javascript
   define("main", [
-    "mojo/services/network/public/interfaces/network_service.mojom",

 ## Final note
 
 An initiator's serviceProvider object can be retained and used to
 request or provide services at any time, not just from within
 application's acceptConnection() method.
