 ### Running tests
 
-Before running the tests make sure that the project is built. To build the 
-project once you can use:
-
 ```bash
-ng build
+ng test
 ```
 
-With the project built in the `dist/` folder you can just run: `karma start`. 
-Karma will run the tests and keep the browser open waiting to run again.
+Tests will execute after a build is executed via [Karma](http://karma-runner.github.io/0.13/index.html)
 
-This will be easier when the command 
-[ng test](https://github.com/angular/angular-cli/issues/70) is implemented.
+End to end tests will be available via `ng test` once implemented ([reference](https://github.com/angular/angular-cli/issues/103))
