Does MetaMask support arbitrum?

I'm curious about the compatibility between MetaMask and Arbitrum. As a user of MetaMask, I'm interested in exploring the potential benefits of using Arbitrum for my cryptocurrency transactions. Can you clarify whether MetaMask supports Arbitrum and, if so, how the integration works? Is there any additional setup or configuration required to enable this functionality, or does it work seamlessly out of the box? Understanding the compatibility between these two platforms will help me make an informed decision about my cryptocurrency wallet and transaction options.
