Yes! Sadly a lot of people skip over this despite vimtutor pointing to it at the end. Copy/paste below as the text doesn't need paraphrasing, but also because a lot of comments here seem to be advocating vimtutor as something more than the "brief overview" it is.

    This concludes the Vim Tutor.  It was intended to give a brief overview of
    the Vim editor, just enough to allow you to use the editor fairly easily.
    It is far from complete as Vim has many many more commands.  Read the user
    manual next: ":help user-manual".

The vim help files are fantastic. Well written, and clearly explain any feature you need to understand better.
