I was at the point where I was creating a new instance(node2) and check pinging it. At that point, the tutorial which was guiding me disappear and I was lost in the middle of the session.
I tried commands like `help` but it didn't help.
When you create the new node (node2), focus automatically switches to that one.
Tutorial was running on node1, so you should be able to continue by clicking on "node1" from left.
