Provide a better explanation of what script does in Readme.MD

[dijuremo]

Would it be possible to provide a clearer explanation on what the script does? Does it automatically add the items to the cart?

I am unable to see the script enabled anywhere when I visit for example the RTX 3090 page. However, clicking on the cart itself, it does show the red bar at the bottom. Found the Whitelisted Keywords and adjusted to match only what I am interested on: 3080ti,3080 ti,3090

So what now? Do I just keep a Bestbuy page open and if the item comes in stock, it will be automatically added to the cart?
