How do I add Starknet to MetaMask?

Could you kindly explain to me the process of adding Starknet to MetaMask? I'm a bit unfamiliar with the technicalities and would greatly appreciate a step-by-step guide. Could you start by outlining the prerequisites I need to fulfill before proceeding? Also, would you mind clarifying any potential risks or security considerations I should be aware of? Finally, is there a specific version of MetaMask or Starknet that's recommended for this integration? Thank you in advance for your assistance.
