-	See description of 'update' command in linkgit:git-submodule[1].
-
-submodule.<name>.branch::
-	The remote branch name for a submodule, used by `git submodule
-	update --remote`.  Set this option to override the value found in
-	the `.gitmodules` file.  See linkgit:git-submodule[1] and
-	linkgit:gitmodules[5] for details.
-
-submodule.<name>.fetchRecurseSubmodules::
-	This option can be used to control recursive fetching of this
-	submodule. It can be overridden by using the --[no-]recurse-submodules
-	command-line option to "git fetch" and "git pull".
-	This setting will override that from in the linkgit:gitmodules[5]
-	file.
-
-submodule.<name>.ignore::
-	Defines under what circumstances "git status" and the diff family show
-	a submodule as modified. When set to "all", it will never be considered
-	modified (but it will nonetheless show up in the output of status and
-	commit when it has been staged), "dirty" will ignore all changes
-	to the submodules work tree and
-	takes only differences between the HEAD of the submodule and the commit
-	recorded in the superproject into account. "untracked" will additionally
-	let submodules with modified tracked files in their work tree show up.
-	Using "none" (the default when this option is not set) also shows
-	submodules that have untracked files in their work tree as changed.
-	This setting overrides any setting made in .gitmodules for this submodule,
-	both settings can be overridden on the command line by using the
-	"--ignore-submodules" option. The 'git submodule' commands are not
-	affected by this setting.
-
-submodule.<name>.active::
-	Boolean value indicating if the submodule is of interest to git
-	commands.  This config option takes precedence over the
-	submodule.active config option. See linkgit:gitsubmodules[7] for
-	details.
-
-submodule.active::
-	A repeated field which contains a pathspec used to match against a
-	submodule's path to determine if the submodule is of interest to git
-	commands. See linkgit:gitsubmodules[7] for details.
-
-submodule.recurse::
-	Specifies if commands recurse into submodules by default. This
-	applies to all commands that have a `--recurse-submodules` option,
-	except `clone`.
-	Defaults to false.
-
-submodule.fetchJobs::
-	Specifies how many submodules are fetched/cloned at the same time.
-	A positive integer allows up to that number of submodules fetched
-	in parallel. A value of 0 will give some reasonable default.
-	If unset, it defaults to 1.
-
-submodule.alternateLocation::
-	Specifies how the submodules obtain alternates when submodules are
-	cloned. Possible values are `no`, `superproject`.
-	By default `no` is assumed, which doesn't add references. When the
-	value is set to `superproject` the submodule to be cloned computes
-	its alternates location relative to the superprojects alternate.
-
-submodule.alternateErrorStrategy::
-	Specifies how to treat errors with the alternates for a submodule
-	as computed via `submodule.alternateLocation`. Possible values are
-	`ignore`, `info`, `die`. Default is `die`.
