1)    This is what you want to undo
2)    This is most often done when you remembered what you just committed is incomplete, or you misspelled your commit message, or both. Leaves working tree as it was before "reset". (The quotes are required if you use zsh)
3)    Make corrections to working tree files.
4)    Stage changes for commit.
