How can I create an angularJS app without using a seed?

From my understanding, this is probably the best way to make an angularJS app: clone this repo http://ift.tt/LzTlnP and then change what you need. However, how would you make an Angular app completely from scratch? I would like it to get it to the state where I can just add app.js/script.js and index.html and just start coding. Thanks.
