yugabyte/yugabyte-db ? reverse-engineered prompt

I want a simple local setup for YugabyteDB that I can run on my machine and try out without a lot of manual work. Please make it easy to start a small cluster, connect to it like a PostgreSQL database, create a table, insert a few rows, and query them back. If possible, include a small sample app or script that shows the database staying available if one node stops, so I can see the resilience piece in action.

I’d also like a clear README style walkthrough for starting, checking status, and shutting everything down, plus any helper scripts needed to make that smooth. Keep it focused on the basic happy path, but make sure it feels polished and beginner friendly. Look up current docs online if you need to, and use the existing project setup where it makes sense.
