The first step to start farming tokens in Curve is to deposit and stake your funds into a Curve pool. This can be done by selecting the pool you wish to farm and then depositing your funds into it. Once your funds are deposited, you can then stake them in the pool and start earning rewards. Staking your funds will enable you to earn rewards in the form of Curve tokens, which can then be used to purchase other tokens or used for other purposes. Additionally, you can also increase your rewards by increasing your stake in the pool, as the more you stake, the more rewards you will earn.
