This will make the submodules HEAD be detached unless `--rebase` or
`--merge` is specified or the key `submodule.$name.update` is set to
`rebase`, `merge` or `none`. `none` can be overridden by specifying
- `--checkout`.

If the submodule is not yet initialized, and you just want to use the
setting as stored in .gitmodules, you can automatically initialize the

-f::

This option is only valid for the update command. Instead of using
the superproject's recorded SHA-1 to update the submodule, use the
- status of the submodule's remote tracking branch. The remote used
+ status of the submodule's remote-tracking branch. The remote used
is branch's remote (`branch.<name>.remote`), defaulting to `origin`.
The remote branch used defaults to `master`, but the branch name may
be overridden by setting the `submodule.<name>.branch` option in

SHA-1. If you don't want to fetch, you should use `submodule update
--remote --no-fetch`.

+Use this option to integrate changes from the upstream subproject with
+your submodule's current HEAD. Alternatively, you can run `git pull`
+from the submodule, which is equivalent except for the remote branch
+name: `update --remote` uses the default upstream repository and
+`submodule.<name>.branch`, while `git pull` uses the submodule's
+`branch.<name>.merge`. Prefer `submodule.<name>.branch` if you want
+to distribute the default upstream branch with the superproject and
+`branch.<name>.merge` if you want a more native feel while working in
+the submodule itself.

--merge::
This option is only valid for the update command.
Merge the commit recorded in the superproject into the current branch
