        Update the registered submodules, i.e. clone missing submodules and
        checkout the commit specified in the index of the containing repository.
        This will make the submodules HEAD be detached.
++
+If the submodule is not yet initialized, and you just want to use the
+setting as stored in .gitmodules, you can automatically initialize the
+submodule with the --init option.
 
+summary::
+       Show commit summary between the given commit (defaults to HEAD) and
+       working tree/index. For a submodule in question, a series of commits
+       in the submodule between the given super project commit and the
+       index or working tree (switched by --cached) are shown.
 
 OPTIONS
 -------
--q, --quiet::
+-q::
+--quiet::
        Only print error messages.
 
--b, --branch::
+-b::
+--branch::
        Branch of repository to add as submodule.
 
 --cached::
-       Display the SHA-1 stored in the index, not the SHA-1 of the currently
-       checked out submodule commit. This option is only valid for the
-       status command.
+       This option is only valid for status and summary commands.  These
+       commands typically use the commit found in the submodule HEAD, but
+       with this option, the commit stored in the index is used instead.
+
+-n::
+--summary-limit::
+       This option is only valid for the summary command.
+       Limit the summary size (number of commits shown in total).
+       Giving 0 will disable the summary; a negative number means unlimited
+       (the default). This limit only applies to modified submodules. The
+       size is always limited to 1 for added/deleted/typechanged submodules.
 
 <path>::
        Path to submodule(s). When specified this will restrict the command
