New here

Hello steemians, I am new here and was trying to figure out what the community is about but the more I read the more confused I got. So please i was wondering if someone could clear the air out and make a post about what we are expecting from the community and what the community expects from us..
I think I speak for others when I say it will help to have a pinned post or some sort of guide as I am looking for new communities to actively participate in..Thank you very much.
