Yeah, though getting useful information out of documentation is a skill on its own that not everyone possesses. But I agree that “it’s in the manual” can be useful, especially these days with how common useless manuals are.

Like I just bought a motherboard and the paper manual it came with was useless, like it didn’t even differentiate between installing Intel or AMD coolers, so clearly didn’t contain much specific information for that particular board.

The online manual had more useful information, unless you want more info about uefi settings, where you’ll be lucky if it has full information of uefi options for the release uefi, let alone the latest version.
