# Simple rewards farming The most classic design of Yield Farming. If some strategy provides claimable rewards for a token, Tetu developers can create a strategy for automating this process. When depositing in the vaults, the strategies will claim the rewards and sell them for the underlying tokens. This process will increase the underlying assets of each user participating in the vault over time, this is called [autocompound](/tetu-io/tetu-v1/yield-farm/vault-shares.md). There are vaults that work according to PS ratio. The PS ratio determines the rate of rewards that will be distributed between the auto compound of the underlying vault and the then divided by the Profit Destination ratio to xTETU Profit Share, Protocol Owned Liquidity, and the Investment fund. The [PS ratio](https://docs.tetu.io/tetu-io/profit-sharing-pool#ps-ratio) has been in existence since the inception of Tetu, the purpose of the PS ratio is to keep yield farming vaults attractive and it is adjusted through DAO voting. The dxTETU holders decide whether it is changed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
