How do I add AirDAO to MetaMask?

Can you please guide me through the process of adding AirDAO to MetaMask? I'm having some difficulty understanding the steps. Specifically, I'm not sure how to locate the contract address for AirDAO and how to add it to my MetaMask wallet. Additionally, I'm wondering if there are any specific settings I need to adjust within MetaMask to ensure a smooth and secure transaction. Any assistance you can provide would be greatly appreciated.
