key points
git diff compares changes in the "working directory" before adding them to the "staging area"
git checkout create and switch between branches
HEAD refers to the most recent commit in the "working directory"
origin refers to the most recent commit in the "remote repository"
if your HEAD is before origin, then you need to pull
if your origin is before your HEAD, then you need to push
narrative
when we pull from remote, the HEAD is sync with origin
practically, HEAD is the local tip you are editing, while the origin refers to the last common point between the local and the remote
when adding local commits, your HEAD advances with respect to the origin
to sync back again HEAD and origin, then push your commits
also
if the remote has new commits, git status tels you that your branch is behind origin/main by the number of commits, suggesting you to pull to update local branch
