Individual Developer (Standalone) commands are essential for anybody who makes a commit, even for somebody who works alone.
standalone developer does not exchange patches with other people, and works in a single repository, using:

git-init(1) to create a new repository.
git-log(1) to see what happened.
git-checkout(1) and git-branch(1) to switch branches.
git-add(1) to manage the index file.
git-diff(1) and git-status(1) to see what you are in the middle of doing.
