How do I set up DeFi?

Could you please guide me through the process of setting up DeFi? I'm new to this and want to ensure I do it correctly. What are the steps I need to follow? Do I need to have a certain level of technical expertise, or can I manage it with basic knowledge? Are there any risks I should be aware of? Additionally, what are some recommended platforms or wallets to use for DeFi? Thank you for your help!
