Before starting to run a node I would strongly recommend to ask yourself: WHY do you want to run a node and depending on the answer, act accordingly. There are many ways and solutions.

I wrote several guides and articles about running node, as I am an old LN node runner too, from beginnings of 2019. Inside my guides you will find more LN documentation and tutorials.

• Read here the introduction on this guide about WHY running a LN node
• Which node software I could run?
• Lightning node fees experiment
• Recommendations for new LN users
• Lightning node maintenance
• Getting started with LN

As LN implementations, my experience was this:

• CLN = stable, strong, light resources, various plugins, if you want a serious node, run CLN
• LND = buggy, using more resources, lots of apps, for beginners is good to start learning
• Eclair = stable, light resources, trampoline channels, few apps supported, more for specific apps and solutions, used in Phoenix
• Rust = stable, trampoline channels, used in Electrum, is a powerful implementation but less used.
• Immortan = light resources, designed for mobile apps (see SBW.app), hosted channels
• LDK = Lightning developing Kit, I think the name say it all.
