citusdata/citus ? reverse-engineered prompt

I want to get this project running locally and make it easy to try out Citus without a lot of manual setup.

Please set up the repo so I can build it from source, start a local Postgres with the Citus extension, and quickly create a small distributed cluster with a coordinator and a couple worker nodes. If there are any missing setup steps or docs gaps, fill them in so a normal person can follow along.

It would also be great if you add a simple example that shows the main thing Citus does, like creating a distributed table, adding worker nodes, and running a query across the cluster. If you need to check current build or install details online, go ahead and do that.
