Integrate bpmn-js npm package in html file

Hello every body,
I have installed bpmn-js package with npm;
now i want to use the library in an HTML file, but i don’t know to do this.
Can you tell me how to organize my project structure to be able to integrate the bpmn-js in my html file.
I followed the examples given in the git repository of bpmn-js, but he don’t work.
Thank you.

Please do not ask the same question twice. Using the npm package in an application is described in this example.
