Add a 2nd and 3rd node to a elasticsearch cluster

Hello, I have set up a 1 node elasticsearch cluster. I have pushed my data and set up security (xpack)

now, that I know it runs OK, I want to add 2 nodes to it to reach a 3 node cluster.

How can I proceed? is there a best practice? If I do it with 2 steps: add the 2nd node then the 3rd, I may have the split brain issue, right?
