A branch is a named reference to the HEAD of a sequence of commits.
A git repo has a current branch (indicated by a \\* in the list of branch names printed by the git branch command), Whenever you create a new commit with the git commit command, your new commit becomes the HEAD of the current branch, and the previous HEAD becomes the parent of the new commit.
A new branch will have the same HEAD as the branch from which it was created until something is committed to the new branch.
