Ok, I understand grokking, a martian term that literally translates as "drink" 
(yes, I know my old science fiction). And, I understood that I need to find the 
book "Git for Teams".


The rest of that is as confusing as you would expect it to be.

Ok, so a remote tracking branch isn't actually a remote branch. Origin/master 
is not master. You've actually got the case of two different "masters" in two 
different versions of the same project that you (maintain? Help maintain? 
Sign-off on?). And a pull request is not a pull request.

Did I understand that correctly?
