Adding new zero nodes

After exporting from 21.12 to 22 and using a single zero node during bulk loading I’m stuck with that zero node. Is there some kind of tutorial on adding new zero instances to the cluster?
Should i just specify existing zero as a peer, copy all other settings from it and launch them?

Seems like there is nothing on this in the docs. Would be great if it eventually got updated.

Yeah, it should be like this. Have you tried and failed? let me know.
