ngCordova installing instructions

I am new for coding and start to work with ioinicframework...

Trying to figure out how to customize the 'splash screen' and trying to setup ngCordova. (using this link: http://learn.ionicframework.com/formulas/splash-screen/)

Where exactly should I inject this line?

Inject as an Angular dependency

Then, include ngCordova as a dependency in your angular module:

angular.module('myApp', ['ngCordova'])"

You will also need to declare it as a dependency of your AngularJS app:

var app = angular.module('yourAppAName', ['ionic', 'ngCordova'])
