    Git init make .git directory and prepare to manage directory by git.
    I think it is necessary process.

How is the staging area different from the working directory and the repository?
What value do you think it offers?

    Staging area is candidiates for repository, so user can edit candidates
    and make commit after deep consideration using staging area.

    same time, it will helpful to keek history.

What is the result of merging two branches together? Why do we represent it in
the diagram the way we do?

    The result of merging two branches is one united branch, so two different
    modifications in two branches can use in master branch.
    Because two different branches are merged in one branch, so we draw these
    way as we do. But I think after merging branches, we just can draw
    just one long line branch, because two branches become one branch.
    In this case, each commit's parent can be confused.

What are the pros and cons of Git’s automatic merging vs. always doing merges
manually?

    Automatic merging
        Pros : Don't annoying, because git merge two branches and user doesn't
               do anything.
        Cons : If one branch's works don't need to new merged commit,
               user delete after automatic merging.

    Manual merging
        Pros : User can select new merging commit's contents.
        Cons : To difficult and may cause low productivity.
