browser version?

Dear Amida-Tech!

I'm currently trying to move from https://github.com/blue-button/bluebutton.js to https://github.com/amida-tech/blue-button. However, I can't seem to find a browser version js that I can just add to my html.

I'm not super well versed in JS, can you let me know where I can find (or how I can create) the browser version js?

Thanks!
Justin
