     * Transfer size:
       In its current form Git requires the whole working tree present. It
       does not allow partial trees to be transferred in fetch or clone.
+      If you have your project as multiple repositories tied together as
+      submodules in a superproject, you can avoid fetching the working
+      trees of the repositories you are not interested in.
     * Access control:
       By restricting user access to submodules, this can be used to implement
       read/write policies for different users.
