 # JQuery Example
 
-This example exposes a simple service at the route `http://localhost:3000/flakeyService`. As the service receives requests, it gets slower and slower. Once it takes more than 1 second to respond, the service just returns a `423 (Locked)` error.
+This example exposes a simple service at the route `http://localhost:3000/flakeyService`. 
+For every request the service receives, the response time is increased.
+[The service returns a `423 (Locked)` error if the response time is above 1000ms.](https://github.com/bucharest-gold/opossum/blob/master/examples/jquery/index.js#L43-L46) This example also has a web frontend at `http://localhost:3000/` for interacting with the service.
 
-Start the server.
+To build and run this example:
 
-```sh
-$ npm start
-```
+1. From the root of the opossum repository, build the `opossum` module:
+  ```sh
+  $ npm install 
+  $ npm run build:browser
+  ```
+  This builds the `opossum.js` file [used in this example](https://github.com/bucharest-gold/opossum/blob/master/examples/jquery/index.js#L21). You only need to do this once.
+
+1. Navigate to the `examples/jquery/` directory
+  ```sh
+  $ cd examples/jquery/
+  ```
+
+1. Start the server.
+  ```sh
+  $ npm install
+  $ npm start
+  ```
+
+1. Browse to the web frontend at `http://localhost:3000` and click the _Flaky Service_ button repeatedly to interact with the service. 
+  Notice the response time increases with every interaction. Once the response time is greater than the [timeout setting](https://github.com/bucharest-gold/opossum/blob/master/examples/jquery/app.js#L16), the [fallback action](https://github.com/bucharest-gold/opossum/blob/master/examples/jquery/app.js#L23) is triggered.
 
-Browse to `http://localhost:3000` and click the button to see the service in action.
