How to add zkEVM mainnet to MetaMask?

Could you please guide me through the process of adding the zkEVM mainnet to my MetaMask wallet? I'm a bit unsure of the steps involved and would appreciate a clear, concise explanation. Specifically, I'm looking for information on how to access the network settings, enter the necessary details for zkEVM, and confirm the addition to my wallet. Additionally, are there any potential security concerns I should be aware of when adding new networks to MetaMask?
