Ok, time to ask for some help - been trying to get the hang of this place through using and so far when I try to search for information I get generic info about what Farcaster is, is there a docs of tut out there that really goes over some of the concepts here that's fairly complete?

Things I'm still not getting:

Also, how the hell do I access some of these dapps? I can't seem to find my "login with mobile" scanner in WC or FQ, is there something I'm missing/what is my FID and is it akin to a public address or should I treat that like a secret key?
