AngularJS which file to add dependency to?

Question

JavaScript

I'm trying JS framework lumx . It is written that for work you need to install the AngularJs dependency:

Use the AngularJS directives and services
When you have downloaded all the dependencies you need to add dependencies on the LumX AngularJS module:

angular.module('myModule', ['lumx']);
What does it mean? Where to enter it?

Answer 1

is it right above the body to write? But then this piece is visible on the page!
I also don't have the visual effect of clicking the button. Although included all js and css (bower).
