I wouldn't say essential, but definitely a useful set of instructions. I myself never bought binoculars or started reading charts or maps, instead I learned the basics about the planets in our solar system and after buying a telescope I am starting to get more in depth with info. I guess what I'm trying to say is, if you're also a beginner like me, and you haven't followed those instructions, then don't be sad. You can still learn more, it's not a step by step process.
