Git users can now take advantage of submodules in their repositories. Until now, submodules could not be deployed using Viaduct.
Each time you deploy your submodules will be updated from their source automatically. Please be sure that if any of your submodules have restricted access, that you add you permit your application's private key access to them.
Submodules with are only authenticated by an HTTP username & password are not currently supported.
You don't need to do anything to enable these, if your repository contains a .gitmodules file, submodules will be included automatically.
