In simpler terms, you can deposit your $RLY holdings into one of the liquidity pools, which will reward you with more $RLY. This process is called staking. You are staking a liquid asset, in this case $RLY, like you would when you put cash into a savings account. Based on the amount and length of time you stake, your stake will yield rewards in the form of more $RLY tokens. You can then move these rewards, or harvest, to your Ethereum wallet and come back to this doc for all the things you can do with your $RLY holdings!
