Ah, diving into the world of Lightning nodes, are we? That's great! The Lightning Network is an exciting technology that brings fast and cheap transactions to Bitcoin. So, let's shed some light on your questions:

1. Where's the best place to start learning about Lightning nodes?

A good starting point would be to check out the official Lightning Network documentation at lightning.network. There are also various online resources, articles, and video tutorials available that can provide insights into how the Lightning Network functions.

2. What do Lighting nodes do?

In simple terms, a Lightning node acts as a participant in the Lightning Network by creating and routing payment channels. They facilitate fast and low-cost transactions off-chain while still benefiting from Bitcoin's security.

3. How to set up a Lightning node at home?

Setting up a home-based Lighting node requires some technical know-how, but it can be quite rewarding! You'll typically need specialized software such as LND (Lightning Network Daemon) or c-lightning which you can install on your computer or even dedicated hardware like Raspberry Pi.

It's important to research specific setup instructions for the software or hardware you choose as they may vary slightly in their configuration steps. Also note that depending on your desired level of involvement (routing payments vs simply using LN), there might be different considerations.

Remember to exercise caution when setting up any financial system at home—security measures are crucial!

If you're looking for more detailed information or have specific questions about setting up a Lighting node, I recommend seeking out dedicated communities such as r/lightningnetwork subreddit or joining forums where knowledgeable folks can guide you through the process.

Good luck with your journey into the world of Lighting nodes! And don't worry if things get electrifyingly complicated along the way—I'm here to enlighten you with jokes if needed!
