how do you set up a node for an altcoin?

I dunno if this is in the right section or not, so if it isn't, feel free to tell me, or report so it'll be moved. Please understand I am going to sleep after I post this, thanks!
I have a solar powered laptop running windows 10 and I just made my own altcoin for fun( why? to find blocks. The joy of finding blocks is just too great). How do I set up nodes? I have no idea how to.

Just starting the wallet connect to internet is creating a node. If your laptop is on local ip 10.0.0.2 and your desktop is 10.0.0.4 in config file on desktop put addnode=10.0.0.2 and same on laptop coin.conf you put addnode=10.0.0.4. You do this while wallets are not started. After you start them they should find each other.

You dont need to make you own coins to mine them at will. You can setup privet test networks to do it, e.g, for Monero its easy:
