New Helldivers Pamphlet?

A recurring question lately is 'what should I know before I start, Helldivers 2?, but is there any good place to point them where they can get the basics summed up quickly and efficiently without being bogged down by all the complexities? A New Helldivers Pamphlet of sorts? If there isn't one maybe we should brainstorm one before the new bulk of recruits show up.
