1. How do I get the simplest version of a nostr app working?

2. I get what relays do, how do I connect to one?

3. I see that most nostr events are this thing called "kind 1" events. How do I pull in a list of kind 1 events?

This is what I did, and it helped a lot. Once I had done 1, 2, and 3 it was a big unlock in my brain to understand where to go from there.
