Re: [PATCH v3 2/3] doc: git-add: clarify intro & add an example

>  DESCRIPTION
>  -----------
> -This command updates the index using the current content found in
> -the working tree, to prepare the content staged for the next commit.
> -It typically adds the current content of existing paths as a whole,
> -but with some options it can also be used to add content with
> -only part of the changes made to the working tree files applied, or
> -remove paths that do not exist in the working tree anymore.
> -
> -The "index" holds a snapshot of the content of the working tree, and it
> -is this snapshot that is taken as the contents of the next commit.  Thus
> -after making any changes to the working tree, and before running
> -the commit command, you must use the `add` command to add any new or
> -modified files to the index.
> +Add contents of new or changed files to the index. The "index" (also
> +known as "staging area") is where Git stores the contents of the next
> +commit.

> +When you run `git commit` without any other arguments, it will only
> +commit staged changes. For example, if you've edited `file.c` and want
> +to commit your changes to that file, you can run:
> +
> +   git add file.c
> +   git commit
> +
> +You can also add only part of your changes to a file with `git add -p`.
