Grasshopper: Found great video tutorials but just need a written one

Per the title. I’m just looking for good written tutorials. Even paid for a low price. My concern is that paid is often worse than free :-S . And per the title, I’ve found really great videos, but a written/web format would really suit my goals at the moment. There’s such a vast sea of information I thought best to get some recommendations.

For what it’s worth I’m doing relatively simple stuff compared to most of you: Just basic 3d geometry. I also want to do quick annotations.

Bonus question: Is there a better/quicker way to delete stuff in grasshopper? I’m having to use the “delete” key on my keyboard which I find a little awkward.

Thanks all!
