The instruction in the wiki instructs the user to run ./scripts/feeds install -a, which doesn't override some core packages and causes some packages from feeds to not appear in the menu, along with a lot of warnings:

These warnings are harmless, but the packages don't seem to appear would be much more puzzling to a beginner, especially when they wanted to install things that relies on libcurl or want usbutils but can't find the packages in the menu?
Assuming there are no addiitional package feeds configured, would it be advisable to put in another section in the wiki to suggest the user to force install either: everything in the feed, or the missing dependency/package they're looking for?
