Get yourself familiar with what the platform is all about by reading about it first in your own language,
or being enlightened by the person that introduce you (if you were).
If your country of origin actually has a local board it could be a very good place to start with on the forum, if you do not have a local board, and you somewhat understand English, then you'll have zero problems familiarizing yourself with what the forum is all about. On the second point, I don't quite agree, majority of people who were introduced to the forum by people were told stories of how they can earn X amount of dollars by posting on the forum, quite a lot of users only expunged that ideology/mindset when they actually started posting on the forum and discovered it's benefits outside earning, as for those who stuck to what they were told, they either got banned for plagiarism/spamming or just grew into constant shitposters with zero development.
Having said that, one doesn't even need all this hackneyed instructions, what you basically must know is that this is a discussion forum for Bitcoin and other crypto related stuffs, just read and follow the rules and you'd be totally fine.
