I dont get what origin and remote both mean. Also, what is origin/master branch?? is it another kind of branch? but if i type "git branch" i only have one branch called "master". It doesnt make any sense. now im confused. help me pls ps. also on exercise 5.git merge when i do the command "git merge origin/master" it says that it is already up to date. And i cant go on to the next section.
