<repository> is the URL of the new submodule's origin repository.
This may be either an absolute URL, or (if it begins with ./
or ../), the location relative to the superproject's origin
-repository. If the superproject doesn't have an origin configured
+repository (Please note that to specify a repository 'foo.git'
+which is located right next to a superproject 'bar.git', you'll
+have to use '../foo.git' instead of './foo.git' - as one might expect
+when following the rules for relative URLs - because the evaluation
+of relative URLs in Git is identical to that of relative directories).
+If the superproject doesn't have an origin configured
the superproject is its own authoritative upstream and the current
working directory is used instead.

init::
Initialize the submodules, i.e. register each submodule name
and url found in .gitmodules into .git/config.
+ It will also copy the value of `submodule.$name.update` into
+ .git/config.
The key used in .git/config is `submodule.$name.url`.
This command does not alter existing information in .git/config.
You can then customize the submodule clone URLs in .git/config
checkout the commit specified in the index of the containing repository.
This will make the submodules HEAD be detached unless `--rebase` or
`--merge` is specified or the key `submodule.$name.update` is set to
- `rebase` or `merge`.

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

If `--recursive` is specified, this command will recurse into the
registered submodules, and update any nested submodules within.

+If the configuration key `submodule.$name.update` is set to `none` the
+submodule with name `$name` will not be updated by default. This can be
+overriden by adding `--checkout` to the command.
