Pull request walk-through

Need some help with my first PR. I have found one that I would like to contribute to but I have never built a desktop application or any application for that matter so the semantics are a little advanced for me. I have only been coding 4 months and I feel like I’m in over my head. If you are seasoned in JS and have some spare time to help a newbie out please reply to this post or message me.
