I agree on CLI text editors. I get why they exist, but for most users they should be a last resort, not the primary instruction.

Instead of telling people to use Nano, just tell people to edit the .conf in a text editor and let them choose!

Many users won't understand that what they're being told to do with Nano is literally just edit a text document with a funky file extension, and that they don't actually have to that it in CLI (in-fact it might even be easier not to if you're not familiar with them).
