How to lend Crypto on AAVE?

Could you elaborate on the process of lending cryptocurrencies on AAVE? As a newcomer to this platform, I'm curious about the steps involved. Firstly, how do I deposit my digital assets onto AAVE? Do I need to have a specific wallet or can I use my existing one? Once my funds are deposited, how do I decide which assets to lend and for how long? Are there any risks I should be aware of, such as liquidity issues or smart contract vulnerabilities? Finally, how do I withdraw my funds and the earned interest? I'd appreciate a step-by-step explanation to help me navigate the lending process on AAVE.
