I know there is three type of full node: 1- mainnet 2- devnet 3- testnet
I wand to build private IoTA network with full control.
So, I have found tutorial for private tangle: https://docs.iota.org/docs/compass/0.1/how-to-guides/set-up-a-private-tangle
and also I have found these is IRI-Playbook: https://iri-playbook.readthedocs.io/en/feat-docker/getting-started-quickly.html
I confused about the difference between them?
