I wrote several guides about Umbrel, to help starters. In the end is just a fancy nice web UI for a simple LN node. iF YOU KNOW WHAT ARE YOU DOING, YOU REALLY DON'T NEED THAT FANCY ui.

Read (all) my guides but especially these:

• https://darth-coin.github.io/nodes/bitcoin-ln-node-software-en.html
• https://darth-coin.github.io/nodes/recommendations-ln-node-operators-en.html
• https://darth-coin.github.io/nodes/lightning-node-maintenance-en.html
• more about nodes: https://darth-coin.github.io/nodes/nodes-en.html

btw, one of the 1st step-by-step guides about Umbrel I wrote in 2021
