I realise this is unlikely to be added by the newcomer themselves, but sometimes the simplest "LMGTFY" questions are from people new to a given platform/OS; they haven't yet really figured out where to start to look for things.
It sometimes takes a couple of comments back & forth to figure out they really are new rather than 'lazy', which then gives you a chance to put up a 'Platform 101'-type answer for complete newcomers to a given OS.
This might help gather together this 101-type resource.
A couple of questions have cropped up recently that could benefit from this tag & appropriate newbie-friendly answer, but I don't want to point at one user for this. It's a general issue we do see on occasion.
