How do I add liquidity to QuickSwap?

Hey there, can you explain to me how I can add liquidity to QuickSwap? I'm pretty new to this and I'm trying to get a better understanding of the process. Is it similar to other decentralized exchanges? Do I need to have a specific token pair in mind or can I just add any tokens I want? Also, what are the benefits of adding liquidity and are there any risks I should be aware of? Thanks in advance for your help!
