I am not so "super specialist" in nodes. But indeed I have a lot of experience running nodes for many years, studying and testing stuff. But all at a pleb/hobby level, not professional or business level.

I know my limits and I know for sure that are many other good node runners here. Only that they are not so "talkers", not everybody want to share their experience and knowledge with others. Some of them are afraid to share that knowledge thinking that some others could take their business model or something like that.

And that's way I started writing guides exclusively for bitcoin and LN nodes, few years ago. I saw that the apps were lacking in documentation or it was super technical explained on github, just few lines of how to install and that's it. And new users had no idea what was that. So I start myself testing them and make a nice explained guide about each solution.

For example, I wrote in 2020-2021 the entire troubleshooting guide for Umbrel, with almost 30+ entries, step by step commands, tested by myself.
