How to receive money on Uniswap?

Could you please explain the process of receiving money on Uniswap in a simple and straightforward manner? I understand it's a decentralized exchange, but I'm unsure of the exact steps involved in receiving funds. Are there any specific requirements or procedures I need to follow? Additionally, is there a fee associated with receiving money on Uniswap, and if so, how is it calculated? I'd appreciate it if you could also clarify any potential risks or limitations I should be aware of when using Uniswap for this purpose.
