Lightning Network Links and Troubleshooting?

There used to be a troubleshooting page that Umbrel hosted that I can’t seem to find anymore.
It had tips for getting started, troubleshooting, and a couple dozen links that I I now miss.

Is there another page somewhere I could reference for links to Lightning Network resources, or could we put sut a post in the announcements section?

Link 1 - Getting Started with Umbrel
Link 2 - Tutorial list about nodes and LN
Link 3 - Opening channels

I will try to add the old FAQ page but I need to gather all the commands
