How To Video too old || New changes makes it difficult to Edit

a little disappointed that I can not follow the how to video when there have been changes the past two years. I have tried numerous areas and this video is the best I have with trial and error for 4 hours straight. Github is not user friendly, even if it is to be able to change the color and add a name, I can't even get the original widget to copy over correctly to even advance to making changes.
