How to Get Started with L2?

Hello fellow Ethereans,
I'm so excited that Layer 2 season is finally upon us! I'm an experienced DeFi user but haven't gotten around to any of the L2 options yet. My main focus is getting started with Optimism and Arbitrum. Anyone have any guides they can point me to?
I'm really hoping to move my activities to L2 so I can save on ETH gas fees. Thanks.
