Hey! No worries at all. Editors of all skill levels are welcome and I'm happy to help and share tips.
There's two easy ways to add references to a page, and it comes down to whether you prefer to use the Visual Editor or the Source Editor(code) You can find a brief overview of how to add references for both editing options at the Style Guide.
If you use source editing and you learn better by example, I can fix the references on the page and you can checkout what code I added, just let me know what works best for you.
Also available by Discord if you prefer more communicating real-time-esque. Doesn't matter to me, I receive wiki notifications pretty quickly.
