Github and open source code

Hi there

Thanks in advance for any help from the Knack Community!

I have some open source code that is available on Github for a "How is your heart" calculator. However, I am not sure how to get this in to my code in Knack. I have a page view already set up for it and some of the information that the calculator requires has already been calculated by my Knack App on another age. There is a lot of the following that I have downloaded from the Github page in the following folders - what is the best way to get this in to my Knack App? Do I just copy and paste everything? Or is there an easier way. I am a learner only when it comes to CSS and JS so please be gentle!
