Staking is much easier than setting up a masternode, all you need to do is have a wallet with as much PIV as possible in it, and it needs to be unlocked for staking (if you've encrypted the wallet).  Then a green arrow will appear at the bottom right of the wallet, and you need to keep the wallet open at all times.  Then at some random moment (not predictable) you'll get a staking reward.  It might take several days based on how many PIV you have.
