How do I swap on Uniswap V2?

Hello there, I'm curious about the process of swapping tokens on Uniswap V2. Could you please walk me through the steps involved in making a swap? I'd like to understand the interface, how to connect my wallet, select the tokens I want to swap, and the final steps to execute the transaction. Additionally, I'm interested in knowing if there are any fees associated with the swap and how to minimize them, if possible. Thank you in advance for your help!
