The SushiSwap Farms (Menu) are located here:
The Farm allows users to yield farm Sushi rewards with each new block, based on staking SLP tokens. 2/3 of the rewards are vested for 6 months from the moment you earn them. So if you can, right at this very minute harvest 1 SUSHI, you will have another 2 SUSHI available to harvest exactly 6 months from now.
For information on how to add liquidity and get SLP tokens, please see the "Providing liquidity to our pools" article under our "AMM / Exchange" section.
Detailed step-by-step guide, and video tutorials, coming soon!
